I will now hand feed you the answers to last week's Culinary I.Q. Quiz. Take your time to digest them well.
1. Baking soda and baking powder can be used interchangeably.
False. Not all leavening agents are created equal. Baking soda is pure sodium bicarbonate, a base that needs to be balanced with an acid like buttermilk to counter its acerbic taste. Baking powder, on the other hand, is both a base and an acid (sodium bicarbonate, cream of tartar and starch), and should be blended with another neutral substance like milk. Baking soda is the go-to leavening agent for cookies, while baking powder is used in cakes and biscuits.
2. All fruits and vegetables continue to ripen after picking.
False. Most stone fruits including peaches, plums, and apricots, along with mangoes, pears, bananas, avocados, and tomatoes will further ripen after picking. Others, especially berries, citrus and watermelon will not ripen further once harvested, so pick wisely.
3. Nectarines are a hybrid cross between a peach and a plum.
False. Nectarines are a hairless recessive allele developed from a peach mutation with firmer flesh and a more refined aromatic scent.
4. The "eyes" that sprout on potatoes can be toxic.
True. Potatoes need to be stored in a cool, dry spot to prevent sprouting tendrils called "eyes," a sign that they germinating. Gouge and discard any "eyes" before cooking since these contain a mild toxin the plant creates to protect its offspring.
5. Tomatoes have more cancer fighting lycopenes when cooked.
True. Since these lovely fruits are also fat soluble, blend with a healthy vegetable oil or cheese to boost the bio-availability of this mighty antioxidant.
6. Avocados are loaded with artery clogging, transfatty monsters.
False. Avocados are a cholesterol-free food with heart-healthy mono- and polyunsaturated fats. They also contain glutathione, an antioxidant that actually blocks absorption of fats by the intestine.
7. Braising and sautéing are similar cooking methods for tenderizing meats.
False. Braising first sears the meat at high temperatures, then slowly cooks it at lower temperatures in a liquid, such as a stock or wine in a covered vessel like a Dutch oven. Sautéing uses high heat and fat in a shallow pan.
8. Sweet potatoes are also called yams.
False. These tuber doppelgangers aren't even related — the sweet potato belongs to the morning glory family, while the yam, which is larger, sweeter and less nutritional than its look-a-like is a lily.
9. Peanuts are botanically a legume, not a nut.
True. Other popular legumes include lentils, peas, and carob.
10. To "shock" green vegetables means to place them in an icy bath to halt the cooking process so they maintain their bright green hue and al dente texture.
