Key rule |
| Blanch & shock |
Green vegetables, par-cooking |
Salted boiling water → salted ice water immediately |
| Roasting |
Root veg, cruciferous, anything with sugar |
425–450°F, single layer, dry surface |
| Panroasting |
Brussels sprouts, mushrooms, dense cuts |
Cast iron or stainless, very hot, don't move |
| Pan-braising |
Cabbage, fennel, leeks |
Sear → small splash of liquid → cover → finish |
| Charring |
Eggplant, peppers, scallions, cabbage |
Open flame or broiler; the burnt outside is removed or eaten |
| Purée |
Any cooked vegetable |
Simmer until dead-soft, blend very fine, strain through sieve |
| Grilling |
Zucchini, asparagus, corn, halved lemons |
Dry surface, oiled grate, high heat |
| Quick pickle |
Onions, cucumbers, jalapeños, carrots |
Warm brine (water + vinegar + salt + sugar); ready in 20–30 min |
| Lacto-ferment |
Cabbage (sauerkraut), brine-packed anything |
2% salt by weight; room temp; 5–7 days |
The Purée Method (Universal)
- Sweat aromatics in butter or olive oil (don't brown)
- Add vegetable cut into uniform pieces
- Add stock or water — just enough to cover
- Simmer until completely, fully, collapse-on-a-fork soft
- Transfer to blender — blend 2–3 minutes until very smooth
- Pass through a fine mesh sieve, pressing with a ladle
- Adjust seasoning; add cream or butter to adjust richness and sheen
Texture test: A spoonful held up should drop cleanly and coat the spoon evenly with no graininess.

Rule of thumb: Season green vegetables with acid (lemon, vinegar) only after they come off the heat.
Roasting Rules Summary
- Oven: 425–450°F
- Fat: enough to coat each piece — not swimming, not bare
- Pan: sheet pan with space — crowded = steamed
- Start: don't stir for the first 10–15 minutes — let the contact surface brown
- Test: a knife should slide in with no resistance
Mushroom Sauté Protocol
- Pan (cast iron or stainless) over high heat — no fat yet — until smoking
- Add mushrooms — they will sizzle and immediately weep water
- Resist stirring; let the water evaporate (~4–5 min)
- Once pan is dry and mushrooms are shrinking, add butter + aromatics
- Toss; cook 2 more minutes; season at the end
- Salt only after browning
