All About Salt*
Salt is the foundation of cooking. It enhances flavors, draws out moisture, preserves food, and triggers chemical reactions that transform ingredients. From the 0.25 teaspoon that brightens a tomato sauce to the 2 tablespoons that create a crispy-skinned chicken, salt does more than just make food taste salty. It amplifies sweetness, tames bitterness, and brings balance to every dish.
How to Select
Choose salt based on crystal size and intended use. Table salt dissolves fastest at 0.3mm crystals. Kosher salt measures 1-3mm, perfect for pinching. Sea salt varies from 0.5-4mm. Check labels for anti-caking agents if you want pure salt. Buy iodized for nutrition or plain for pickling.
How to Store
Keep salt in airtight containers away from moisture. Glass jars work best. Add 5-10 grains of rice to prevent clumping in humid climates. Salt stored properly lasts indefinitely. Flavored salts keep 6-12 months before aromas fade. Store finishing salts separately from cooking salts to preserve their texture and prevent contamination.
How to Prep
Measure carefully since brands vary. Diamond Crystal kosher salt weighs 10g per tablespoon while Morton's weighs 19g. When salting pasta water, use 1 tablespoon per 4 cups water. For brines, dissolve 1/4 cup salt per quart of water. Grind coarse salts in a mortar for rubs. Toast flavored salts in a dry pan for 30 seconds to wake up aromatics before using.
Flavor Pairings
Salt amplifies sweetness in desserts at 1/4 teaspoon per cup of sugar. It cuts through fat in butter and cream dishes. Garlic salt combines two powerhouse seasonings. Salt makes bitter vegetables like spinach more palatable. In Mexican cooking, lime and salt create bright acidity. Italian dishes balance salt with parmesan's umami.
Cooking Tips
Salt meat 40-60 minutes before cooking to allow penetration. Use 3/4 teaspoon per pound.
Add 1/8 teaspoon salt to coffee grounds before brewing to reduce bitterness.
Season in layers. Add 30% while cooking, 50% during, 20% at finish for depth.
Test pasta water. It should taste like mild seawater at 1-1.5% salinity.

FAQ
Why do recipes specify kosher salt?
Kosher salt's 1-3mm crystals make it easy to pinch and control. Its pure taste comes from no additives. Most importantly, the larger crystals mean 1 teaspoon of kosher salt contains about 60% as much salt by weight as table salt. This prevents oversalting when cooking by feel. Professional kitchens use it because you can grab exactly what you need.
How much salt should I use when cooking?
Start with 1/2 teaspoon per pound of vegetables or grains. Use 3/4 teaspoon per pound of meat. Pasta water needs 1 tablespoon per 4 cups. Bread dough takes 2% salt by flour weight. Taste and adjust throughout cooking. Remember that reduction concentrates salt, so undersalt sauces that will reduce by half or more.
Can I substitute different salt types?
Yes, but adjust amounts. If a recipe calls for 1 teaspoon Diamond Crystal kosher salt, use 1/2 teaspoon table salt or 3/4 teaspoon Morton kosher salt. Sea salts vary widely. When in doubt, dissolve 1 teaspoon of your salt in 1 cup water and compare taste to the same ratio with table salt. Most conversions fall between 0.5-0.75 ratios.
Why does my salt clump?
Salt absorbs moisture from air at humidity above 75%. Each grain can hold 0.5% its weight in water. Add 5-10 grains of rice per cup of salt to absorb excess moisture. Replace rice every 6 months. For long-term storage, vacuum seal portions or add silica gel packets. Never store salt in metal containers, which can corrode.
