As I delve into the instructional side of the culinary arts, with my intrepid seven-year-old apprentice at my side eager to learn, or at least to wield tools of the trade, I thought I'd open up a thread or three on the basics.
Research on the mother sauces invariably leads back to Escoffier, who updated the famous cook Careme's four sauces into
BETH V or:
B for Béchamel
E for Espagnole or Brown Sauce
T for Tomato Sauce
H for Hollandaise and
V for Veloute
While these sauces sound teriffically difficult, many home cooks use a modified version of them on a regular basis - for instance, roux-based sauces are common in the home kitchen: Espagnole, from what I can gather, is basically gravy (please don't rend your hair, chefs - depending on your definition of gravy; yes, Espagnole is a roux-thickened veggie-fortified stock; at least a kissing cousin of a good pan gravy) Bechamel we all know as white sauce or cream gravy, and appears, slightly modified, in homemade mac-n-cheese and alfredo sauces. Veloute, the base of my beloved
Turkey Tetrazzini, also often a regular contributor to Thanksgiving as gravy. Really, a blond roux is about as easy as it gets, especially if you cheat with superfine flour - equal parts of thoroughly blended flour and fat, sizzled until fragrant, and a hot liquid is whisked in and heated until thickened. 1 tbsp of roux will thicken about 1 cup of liquid; sauces involving dairy can be a little tricky (keep the heat slow) but once you get some successes under your belt, it's pretty easy.
Of all these sauces, it's the egg emulsions that seem to be out of favor: while I've been known to make my own hollandaise or sabayon, I find the process of separating eggs and then figuring out what to do with the leftover whites to annoyingly wasteful to be something I practice on a regular basis. They are, indeed, extremely easy to break (I'm planning a lesson on broken sauces with Sparky) and tough to thicken properly, but sometimes nothing but real hollandaise will do.
There are a couple other sauces every cook ought to know about: Escoffier neglects reductions and jus, which is what I grew up with: my mother always threw wine into the hot pan after cooking steaks, and the resulting wine-y, fond-y jus was our version of gravy. It wasn't until I discovered that the rest of the world added flour to the fat before adding liquid that I started making traditional gravies. Another good one is the blended sauce: tossing everything from the bottom of your roasting pan into an immersion blender gets you something that's not quite a brown sauce, especially if you have lots and lots of root vegetables as your thickener. There's a whole world of other sauces Escoffier didn't deign to notice: chutneys and other fruit-vegetable composites like steak sauce and ketchup, viniagrettes and finishing sauces like gremolatas and composite butters, but it's amazing what a little sauce competency can do for your cooking - sauces can elevate the most humble of meals.
I should follow this with a recipe, but I'm out of time right now - so I leave this thread in the competent hands of my fellow LTHers.
