Ingredients 101

Eating vegetarian isn't just for vegetarians. There are plenty of reasons, health and economics-wise, to consider forgoing the meat for a meal or three. Rather than get deep into the world of fake meat (although there's many a tasty alternative to be found there, to be sure), you should consider getting to know your humble-seeming fungal friend: the mushroom.

Herbs, both fresh and dried, can be intimidating and mysterious to cooks. Just how much is too much? How do you prepare them?

For the novice cook, fungi can be weird because, well, they're fungi. However, if you've been afraid to get acquainted with mushrooms, you've been missing out. Vegetarians love mushrooms and with good reason.

The world of spices can be bewildering. They promise to make your food more flavorful if you know how to make the most of them. Unless you know a couple of essential tricks, however, it just seems like you're adding bits of colored powder to your food.

Go to a chain supermarket, and chances are you'll see one type of garlic—maybe two or three if you're lucky. However, there's a mouthwatering slew of Allium sativum out there, far beyond those papery white bulbs most of us encounter at the nearest Stop 'n' Shop.

Butter can be even more delicious than it already is. While that may be a shocking claim, it's most definitely true. Many new cooks and even seasoned chefs don't realize this, but the few minutes it takes to do these things will pay you back exponentially when it comes to that buttery taste.

People tend to skip toasting nuts in recipes or before adding them to salads because it seems time-consuming and the margin for error is high. However, skipping this step is a big mistake. Why? Because when you skip toasting your nuts (go ahead, you can laugh, we're all doing it), you sacrifice flavor and texture. And not just a little flavor, but a lot. Alton Brown recommends wok-frying peanuts before making your own nut butter for this very reason.

If you've been to a farmer's market during tomato season, chances are you know that heirloom tomatoes are pricier (and funnier-looking) than their hybrid counterparts.

Foodies and big-time chefs like Thomas Keller go crazy for fleur de sel. This finishing salt appears in fancy eateries and cookbooks the world over, and in the early 2000s, it was not uncommon to see diners in a high-end restaurant sprinkle a pinch of fleur de sel on their plates from their own personal stash.

Most recipes don't specify what type they mean when they call for onions. While using whatever kind you already have won't necessarily ruin a dish, using the best one for what you're cooking will definitely make your food taste better.
