Garlic

Buy heads that feel firm and heavy with tight, papery skin. Skip anything soft, sprouting, or with green shoots poking out the top. Store whole heads in a cool, dark spot with airflow (not the fridge, and not next to potatoes or apples), where they'll keep 3–6 months. Once you break a head open, use the loose cloves within 10 days. If a clove has a green sprout in the middle, split it and flick the germ out: these are still safe to eat but will be more on the bitter end. Jarred pre-minced garlic gets a lot of hate. It's okay in a pinch, but it's a penalty I'm not willing to pay. Fresh cloves take 20 seconds to smash and peel.

Garlic is two ingredients pretending to be one: when it's raw or sautéed it's sharp and punchy, but roasted low and slow it turns sweet, nutty, and spreadable like butter. Most people only ever mince it, which means they never meet other fantastic versions of garlic. Cut the top off a whole head, drizzle with olive oil, wrap in foil, and roast at 400°F for about 40 minutes, then squeeze the cloves out like toothpaste for lovely roasted garlic cloves. I personally always keep a jar of garlic confit in the fridge and that golden garlic oil is the closest thing to a cheat code my kitchen has.
