# Chef Vegetable Guide Most home vegetable cookery fails in one of two directions: **boiled into gray mush** or **raw-hearted and unseasoned**. Vegetables are not garnish — each has a correct method and a correct doneness, and salt/fat/acid apply to them exactly as to meat. Read `references/vegetable-tables.md` for per-vegetable methods, temps, and times. ## Universal rules 1. **Water is the enemy of flavor.** Flavor concentrates when water leaves (roasting, searing, grilling) and dilutes when water enters (boiling). Boil only when the water is the dish (soups) or for blanching. 2. **Roast hot: 200–220°C**, cut evenly, tossed in enough oil to coat (1–2 tbsp per tray), in ONE layer with space. A crowded tray steams; two trays beat one pile. Salt before roasting; acid/fresh elements after. 3. **Brown = flavor.** Maillard and caramelization apply to vegetables fully. Pale roasted vegetables are unfinished. 4. **Blanch green vegetables** in aggressively salted boiling water (10 g/L) for minutes, then ice/cold-rinse to lock color. Add acid only at serving — acid + time turns greens olive-drab. 5. **Cut size = cooking method.** Big chunks for long roasts/braises, small dice for quick sautés and soups. Mixed sizes = mixed doneness. 6. **Stagger by density** when combining: onions/carrots/roots first, peppers/zucchini mid, greens/garlic/peas last. 7. **Season vegetables like they matter:** salt during cooking, acid at the end, and a finisher (butter, good oil, nuts, herbs, cheese) on anything served as its own dish. 8. **Doneness target:** tender with a remnant of resistance. If a fork meets zero resistance anywhere, you're in mush territory (except deliberate purees/braises). ## Method-selection logic - Want a side that tastes premium with zero skill → roast at 210°C until deeply browned (cauliflower, broccoli, carrots, potatoes, squash all transform). - Want speed → hot sauté/stir-fry with staged additions. - Want soup → sweat aromatics in fat first (never just boil everything from cold — sweating builds the flavor base). - Want freshness → raw/quick-pickle: salt + acid + 15 min does wonders for onion, cucumber, cabbage, radish. - Want silk → braise (cabbage, leeks, fennel, green beans "southern style") — the deliberate exception to "don't cook long". - Potatoes are their own science: starchy (baking, mash, fries) vs waxy (salads, boiling); never mash in a food processor (glue). ## Frozen & preserved - Frozen peas/corn/spinach are excellent — often better than tired fresh. Do NOT thaw before cooking (except spinach: thaw + squeeze hard). - Frozen "stir-fry mixes" water everything down — roast from frozen at 220°C or accept the compromise. - Sauerkraut/pickles are flavor ingredients, not just sides: brines = acid seasoning. ## Rescue table | Problem | Fix now | Prevent next time | |---|---|---| | Soggy roasted veg | Hot oven 230°C 5–10 min spread out | Less crowding, dry veg, hotter oven | | Gray green beans/broccoli | No rescue; garnish strategy | Blanch + shock; acid only at serving | | Bland soup | Salt %, then umami (tomato paste, parmesan rind), then acid | Sweat aromatics first, season in layers | | Bitter eggplant/zucchini burn | Cut off char, restart heat lower | Medium heat, more oil for eggplant | | Watery sauté | Drain, then hard heat to evaporate | Hotter pan, smaller batches, salt later (mushrooms) |
