Cooking Techniques

Why technique matters more than recipes

A recipe is a snapshot. A technique is a transferable skill. Someone who memorizes 200 recipes can cook 200 dishes. Someone who masters 10 techniques can improvise thousands.

Every cooking technique is a controlled application of heat, time, and medium. The variables: temperature (how much energy), duration (how long), medium (air, water, fat, or direct contact), and surface area (cut size determines cooking speed).

The four heat transfer methods

Method	Medium	Temp range	Best for
Conduction	Direct contact (pan surface)	150–300°C	Searing, sautéing, griddle cooking
Convection	Moving air or liquid	100–250°C	Roasting, baking, boiling, deep-frying
Radiation	Infrared (no medium)	260–540°C	Broiling, grilling, toasting
Induction	Electromagnetic (heats pan directly)	Variable	Any pan-based method, precise control

Most cooking uses multiple methods simultaneously. Roasting a chicken: convection (hot air) + radiation (oven walls) + conduction (roasting pan base).

The Maillard reaction — why browning = flavor

At 140–165°C, amino acids react with reducing sugars to produce hundreds of flavor compounds. This is the Maillard reaction — it’s why seared steak tastes different from boiled steak, even at the same internal temperature.

Requirements for Maillard browning:

• Surface must be dry — water caps surface temp at 100°C (evaporation), blocking Maillard. Pat proteins dry before searing.
• High heat — below 140°C, the reaction is too slow to matter. Pan must be hot before food enters.
• Don’t crowd the pan — too much food drops pan temperature and releases moisture. Cook in batches.
• pH matters — slightly alkaline surfaces brown faster. A pinch of baking soda on proteins accelerates browning (Chinese velveting technique).

Knife skills as efficiency

Cut size controls cooking time. Uniformity controls even cooking. The two rules:

1. Smaller pieces cook faster — more surface area per unit volume means faster heat transfer.
2. Same-size pieces cook at the same rate — irregular cuts mean some pieces burn while others are raw.

Cut	Size	Use
Brunoise	3mm cube	Garnish, soffrito
Small dice	6mm cube	Soups, salsas
Medium dice	12mm cube	Stews, roasted vegetables
Large dice	20mm cube	Chunky soups, pot roasts
Julienne	3mm × 3mm × 50mm	Stir-fry, salads, garnish
Chiffonade	Fine ribbon	Herbs, leafy greens

Sauce fundamentals

Every classical sauce follows the same architecture: liquid + thickener + flavor.

Thickener	Mechanism	Ratio (per 500ml liquid)	Result
Roux (flour + fat)	Starch gelatinization	30g each	Béchamel, velouté
Cornstarch slurry	Starch gelatinization	15g in 30ml cold water	Clear, glossy
Reduction	Evaporation concentrates gelatin	Reduce by 50–75%	Pan sauce, jus
Emulsification	Fat suspended in liquid	Butter whisked into acid	Beurre blanc, vinaigrette
Egg yolk	Protein coagulation + emulsion	2–3 yolks	Hollandaise, custard

The pan sauce is the most practical: deglaze fond (caramelized proteins stuck to pan) with wine or stock, reduce, finish with cold butter for body and shine. Three minutes. No recipe needed — just the technique.

What separates home cooks from professionals

Professionals control heat instinctively. They know:

• When to use high heat (searing, stir-fry) vs. low heat (braising, confiting)
• When to move food (rarely — let Maillard happen) vs. when to stir (risotto, scrambled eggs)
• When food is done by sound (sizzle pitch drops = moisture released), sight (color change), touch (finger test for meat), and smell (nutty = browning, acrid = burning)

None of this requires a recipe. It requires understanding what heat does to food — and that understanding transfers to every dish you’ll ever cook.
