⚖️ Kitchen Differences That Matter

Table salt vs. kosher salt vs. sea salt

By weight, salt is salt. By volume, the crystal size makes a big difference, so a teaspoon of one salt can hold twice as much as a teaspoon of another. UC Agriculture and Natural Resources gives these weights:

• Fine sea salt measures close to table salt; flaky sea salts are much lighter.
• Iodized table salt has added iodine. Kosher salt usually has none, though some brands add anti-caking agents.
• In these recipes, “salt” means table salt. If you use kosher salt, use more by volume, or salt to taste near the end.

Baking soda vs. baking powder

They are not interchangeable. Baking soda is a base and needs an acid in the recipe (buttermilk, yogurt, brown sugar, vinegar) to make bubbles; too much without enough acid tastes metallic. Baking powder carries its own acid. Most is “double-acting”: it rises once when it gets wet and again in the oven.

In a pinch: for 1 teaspoon baking powder, use 1/4 teaspoon baking soda plus 1/2 teaspoon cream of tartar. To replace baking soda, use about three times as much baking powder. Neither swap is perfect.

Salted vs. unsalted butter

U.S. butter must be at least 80% milkfat. Most is sold lightly salted; unsalted is sometimes called “sweet butter.” Salt adds flavor and helps butter keep a little longer. Bakers often prefer unsalted so they control the salt. If you use salted butter in a recipe that calls for unsalted, cut back the added salt slightly. Keep butter in the fridge, or freeze it for up to a year.

Ground beef: 80/20, 85/15, 90/10 and up

The numbers are percent lean and percent fat, so 80/20 is 80% lean and 20% fat. By federal rule, anything labeled “ground beef” can be no more than 30% fat, with no beef fat added; “hamburger” has the same 30% limit but may have beef fat added. If a label names a cut, like ground chuck or ground sirloin, the meat must come from that cut. The redder the meat, the leaner it usually is.

Fattier blends make juicier burgers and more drippings; leaner blends suit sauces and chili, where you would pour the fat off anyway. Whatever the blend, cook ground beef to 160°F, and use or freeze raw ground beef within 1 to 2 days.

In these recipes: 80/20 for burgers, 85/15 for sauces, chili, tacos and meatloaf. Leaner beef works; add a teaspoon of oil to the pan.

Chicken breasts vs. thighs

Breasts (white meat) are lean and cook fast but dry out if overcooked. Thighs (dark meat) have more fat, stay juicy, and forgive a few extra minutes. Both are safe at 165°F. You can swap one for the other by weight; boneless thighs may need a minute or two longer. Bone-in pieces take longer than boneless.

Do not rinse raw chicken; it spreads germs around the sink and does not make the chicken safer. Use raw chicken within 1 to 2 days or freeze it.

All-purpose vs. bread flour (and friends)

• All-purpose flour: about 10 to 12% protein; the everyday choice for most baking.
• Bread flour: about 12% protein; builds more gluten for chewy, high-rising yeast breads.
• Cake flour: made from soft wheat with less gluten, for tender cakes.
• Whole wheat flour: made from the whole kernel; it absorbs more liquid.
• Self-rising flour already has baking powder and salt. To make 1 cup: 1 cup minus 2 teaspoons all-purpose flour, plus 1 1/2 teaspoons baking powder and 1/2 teaspoon salt.
• In these recipes, “flour” means all-purpose.

Dried vs. canned beans

One pound of dried beans (about 2 cups) makes about 6 cups cooked. A drained 15 1/2-ounce can holds about 1 3/4 cups. Dried beans cost less per serving but need soaking and an hour or more of cooking; canned beans are ready to use. Draining and rinsing canned beans removes some of the salt.

Soak dried beans overnight in the fridge or use a quick soak (boil 2 to 3 minutes, then soak at least 1 hour), then drain and rinse. Lentils and split peas need no soaking.

One safety rule for dried red kidney beans: raw or undercooked, they contain a natural toxin (phytohaemagglutinin). Soak them, then boil them briskly in fresh water before adding them to a slow cooker, which may not get hot enough to destroy it. Canned kidney beans are already cooked and safe.

Brown vs. white rice

Brown rice has only the hull removed, keeping the bran and germ; white rice has the bran and most of the germ milled away. Brown rice has more fiber and takes longer to cook. Both swap in most recipes; follow the package for water and time. Cool cooked rice quickly and refrigerate it within 2 hours.

Fresh vs. dried herbs

Use about three times as much fresh herb as dried: 1 tablespoon fresh for 1 teaspoon dried. Add tender fresh herbs (basil, cilantro, parsley, dill, chives, mint) in the last minute or two, or as a garnish; sturdier ones (oregano, rosemary, thyme) can go in for the last 20 minutes.

Stock vs. broth

Stock is simmered with bones, which give it gelatin and body; broth is made mostly from meat and is thinner. Broth can stand in for stock when the body or clarity of the liquid is not important, such as in soups and in sauces thickened with starch, which covers every recipe here. Store-bought cartons vary a lot in salt, so compare the sodium on the labels; a low-sodium carton lets you season to taste.

Heavy cream vs. half-and-half

Only heavy and whipping cream whip. Higher-fat creams hold up better when simmered in sauces; half-and-half is best stirred in near the end over low heat.

"Use by" vs. "sell by" vs. "best if used by"

• Best if Used By/Before: when the product will have its best flavor or quality. Not a purchase or safety date.
• Sell-By: tells the store how long to display the product. Not a safety date.
• Use-By: the last date recommended for peak quality. Not a safety date, except on infant formula.
• Freeze-By: when to freeze for peak quality.
• Except for infant formula, federal rules do not require dates. If a date passes while food is at home, it should still be safe if handled properly, until it shows signs of spoilage like an off smell, flavor or texture. Infant formula should not be bought or used after its Use-By date.
• Food kept frozen at 0°F stays safe indefinitely; freezer times are for quality.
