Couple of Quick Book Suggestions


If you’re in the mood for a food read, pick up a copy of Jacques Pepin’s The Apprentice. It’s a delightful read, portraying some of the last days of old school French cooking via the apprenticeship method. There are some wonderful recipes as well.

Secondly, definitely check out Rowan Jacobsen’s Apples of Uncommon Character. It’s a fascinating look at what Jacobsen  calls The Sexond Age of Apples, the recovery and resurgence of heirloom, regional varieties across the country and the world. And frankly anything else by Rowan is worth your time and money, especially American Terrior if you’ve not already read it.

Enjoy!

Purées


My Nephew Ian comes up with so many good questions that turn into posts, I should have him on the payroll… This time around, he asks “Was thinking about making a cauliflower purée – how do I do that so that it actually tastes good?” The question sparked the realization that I get a lot of questions about purèes, so it’s time to expand on the topic.

Most humans start out eating purées as their first ‘solid’ food; that may explain both the attraction as well as the reticence many adults have with the concept. A purée is basically a sauce, somewhere between a paste and a very thick liquid in consistency. Point of fact, several variants are things we eat quite often, like apple sauce and mashed potatoes. Others are a bit rarer, like the cauliflower Ian asked about. The term is, of course, French – it means to purify or refine, and it’s quite old – My research found references to it all the way back to the 1200s.

Achieving a purée isn’t difficult; foods can be blended, processed, ground or sieved to achieve the desired result. That means that those of you who don’t have blenders or processors won’t be left out – something as simple as a sturdy single mesh strainer, a masher, or an old fashioned potato ricer will work just fine for many foods; a large fork will work in a pinch, too.

When it comes to constructing a tasty purée, a little forethought goes a long way. Potatoes lend themselves selflessly to the process, while that cauliflower requires a bit more effort. In both cases, (as with most foods you purée), cooking is necessary; this achieves several things, from making a food purée-able, to arriving at the desired consistency, and improving overall flavor. Steaming is always a great first cooking choice as it preserves nutrient content better than boiling does. A slow, gentle simmer is another good choice. At a minimum, blanching prior to puréeing takes the raw edge off, and maintains nice, bright colors as well.

Next consideration is water content. You might think that the average spud has more water onboard than cauliflower does, but it ain’t necessarily so – cauliflower is around 92% water, while the potatoes are more like 79%, (root veggies are among the lowest water content of any of the common veggies, one reason they store well.) What that tells us is that the cauliflower is going to require some reduction in water content to achieve a good purée, while the spuds will need some moisture added. Here’s a handy reference for future use.

Next consideration is the overall taste profile – what you’re after with a purée. Foods that have big flavor right out of the chute, like apples and berries, or sweet peppers and fresh peas, don’t need a whole lot of reinforcement to make a great purée – A little spice in the former (cinnamon, vanilla bean, ginger for instance), a little seasoning in the latter (sea salt, fresh ground pepper, a touch of citrus), and you’re good to go. Working with a light touch in either example allows the food being puréed to shine without being overpowered. Now that cauliflower, well… There are certainly folks who like this veggie plain, but it’s a safe bet more of us like some serious augmentation – my version treats it pretty much like mashed potatoes, adding stock, dairy, and fresh herbs, as you’ll see below. Personally, I treat almost all root veggies that way – They’re big on starch and sugar, but can all use some help in the taste arena.

A few final thoughts. A purée is a nice change of pace, and a great way to insert a touch of flavor into every bite of a main course dish. Whatever you purée, a nice, smooth consistency is what you’re after – gritty or lumpy isn’t likely to float anybody’s boat – This is where stock and dairy, (cream, sour cream, butter, and yoghurt are all nice), really shine as an adjunct ingredient. Keep that textural change in mind; make sure there are plenty of other touches, like a little crunch, so that you’re presenting a nice, balanced plate. Consider something a bit outside the box when you’re ready to try one – The herbed blueberry version below goes great with pork or chicken, as a for instance.

Here’s a couple to get you started.

Cauliflower Purée

1 Head Cauliflower

1/4 Cup Vegetable Stock

2 Tablespoons Butter

1 Tablespoon Avocado Oil

1 teaspoon Lemon Thyme

1 teaspoon Sea Salt

 

Rinse cauliflower, pat dry, and cut into roughly 1/2″ chunks.

Place cauliflower in a steamer basket, within a large pot with about an inch of water therein.

Turn heat to medium high until water starts to boil.

Cover pot, reduce heat to low, and steam cauliflower until it mashes easily when tested with a fork, about 15 to 20 minutes.

Transfer cauliflower to a blender or processor. Add stock, oil, butter, lemon juice, and salt. Pulse until a nice, smooth consistency is achieved, about a minute.

Crush lemon thyme by hand and add; add a few twists of pepper. Pulse to incorporate, taste and adjust salt and pepper as needed.

Serve promptly.

Herbed Blueberry Purée

2 Cups fresh Blueberries, (frozen will do fine)

2 Tablespoons Agave Nectar

1 Navel Orange

4-5 leaves Fresh Basil (Cinnamon, or Christmas Basil is spectacular)

Pinch Sea Salt

Rinse blueberries, then toss them into a blender or processor and pulse to a smooth consistency, about 30 seconds.

Cut orange in half; zest and juice half, return the rest to fridge.

Chiffonade basil.

In a saucepan over medium heat, combine berries, honey, zest, juice of half orange, and salt.

Bring mixture to a boil, then reduce heat so blend is at a low simmer; cook for 10 to 15 minutes until blend has reduced and thickened notably.

Remove from heat, add basil and stir to incorporate. Allow basil to steep for 15 minutes as the mixture cools.

Pour the blend into a glass bowl through a single mesh strainer to remove solids and basil leaf.

You can serve just as it is, or allow to cool to room temperature.

Will store refrigerated for 3-4 days.

To serve, heat in a sauté pan, add 1 tablespoon of butter and whisk to incorporate.

Serve hot.

 

 

Baking Soda v. Baking Powder


Here's another great question from reader Pauline all the way over in New Hampshire, on a topic that probably doesn't get asked all that often;

“So, I bake infrequently, and I've got containers of baking soda and baking powder that have been in my pantry forever; do these things go bad? And while you're at it, was is this stuff anyway?

Glad to help, Pauline, and thanks for asking.

The quick and dirty answer to the former question is, yes, they can go bad. Baking soda and powder are chemical leavening agents that promote rising in baked good recipes that don't employ yeast. While the end result is much the same with all three leaveners, the primary benefit imparted by baking soda and powder is speed; they can and should be used right away after mixing, while yeast takes time and really can't be rushed much. The active constituents of both do have a shelf life, albeit a long one. Fortunately, there's a couple of quick test you can do to see if yours still makes the grade.

The first test is to find and read the expiration date; at the risk of being flippant, there are printed dates on the containers of both products, though they may take a bit of sleuthing to find. If yours is past its date, discard it and buy a fresh replacement. When you're at the store, check that expiration date on what you're about to buy; in a professional kitchen, we check the dates on every case that comes in, because it's not that uncommon to find expired product in your just-made delivery, and your local grocery is no exception to that rule.

The second test is for a chemical reaction, and is therefore a bit more definitive. Take a good pinch of baking soda and drop it into some fresh vinegar; if it fizzes actively, you're in business. For baking powder do the same thing into hot water. If either just sit there, toss them

On to the latter question;

Baking soda is pure sodium bicarbonate, an alkaline or base in chemical terms. Combined with moisture and an acidic ingredient like dairy, chocolate, or honey, you get a mild chemical reaction akin to the freshness test you just did. The resulting tiny bubbles of carbon dioxide, (CO2), remain trapped in the batter matrix. Exposed to baking temperatures in your oven, they expand and cause your baked goods to rise. baking soda is a pure chemical base, so it can impart a bitter taste note if you add too much; that said, a little extra is actually a very good thing, for a most interesting reason. Just a bit more baking soda than that needed to neutralize the acid in your recipe contributes in a very positive way to browning and flavor in your finished product. This has to do with the Maillard reaction, named after Louise-Camille Maillard, who first described it about a hundred years ago. What Maillard detailed was a complex set of reactions that lead to such culinary wonders as the luscious crust on your steak, the sweet beauty of caramelized onions, and the golden brown outside of a cream biscuit. On top of the lovely color added, the reaction also produces hundreds of aromatic compounds that add savoriness and complexity; in other words, it's a very good thing indeed. The key is moderation; an eighth of a teaspoon above a stated recipe amount is enough to hit the sweet spot.

Baking powder is a mixture of a base and an acid or acids; sodium bicarbonate is the base, while cream of tartar and sodium aluminum sulfate are the common acids. There's typically a bit of added starch as a carrier for the active ingredients as well. Baking powder is a more complex and balanced leavener than baking soda, since it contains both acid and base; it is completely inert when dry, but when introduced to moisture, the base and acid mix and generate CO2, and you're in business. The reason baking powder is called 'double acting' is the presence of the two different acids. When added to your recipe, the first acid, cream of tartar, mixes with the baking soda and goes to work right away. The second acid, sodium aluminum sulfate, is temperature activated; when your batter or dough hits roughly 175° F, that acid combines with the remaining base and contributes a bit more rise.

 

You can make basic baking powder at home by combining,

2 teaspoons Cream of Tartar

1 teaspoon Baking Soda

1 teaspoon Corn Starch

 

The obvious benefit is fresh product, assuming your constituents are, of course, but this will not be a double acting powder and as such, won't have quite the lifting power of the commercially prepared stuff.

If the aluminum makes you nervous, maybe it should. Aluminum has been found to adversely affect reproductive and nervous systems in animal studies. Some human studies have suggested a possible connection between aluminum and Alzheimer's Disease. The health effects of aluminum on humans are not definitive, but nonetheless, the Joint Food and Agriculture Organization/World Health Organization Expert Committee on Food Additives (JECFA) significantly lowered the tolerable intake of aluminum as a result of such studies.

Some recipes call for baking soda, others for baking powder, and some employ both. The leavener(s) called for is governed by the over-arching recipe. The straight base chemistry of baking soda dictates does well with more acidic ingredients, like buttermilk pancakes, or cake recipes that employ vinegar. Baking powder commonly gets paired with more neutral ingredients like plain milk or non-dairy alternatives.

So how about the interchangeability of these two? You can substitute baking powder in place of baking soda using a ratio of 3:1 powder to soda, but it's not a desirable substitute; the significant amount of added acid will impact the taste of your finished product. On the other hand, you cannot sub baking soda for baking powder, since baking soda lacks the acidity needed to make things rise.

With both these leavening agents, it's important to keep in mind that the reaction produced is relatively short lived and begins as soon as you mix ingredients. It's always best practice to have your oven preheated and to bake promptly, otherwise you'll miss the window of efficacy and your goodies will fall flat. Unlike a yeasted dough, which is relatively low in moisture and kneaded until a tough, elastic gluten network is produced that will trap massive amounts of carbon dioxide, quick batters and doughs are made with an extremely moist batter, because baking powder just doesn't generate enough gas to effectively leaven a thicker dough. Additionally, batters have relatively little gluten formation, so they're not that meaning that great at trapping and holding bubbles.

That's probably all you need to know about that.
