Kitchen glossary
The words recipes assume you know.
Short, plain definitions of cooking terms, from al dente to zest. Look one up mid-recipe and get back to the stove.
A
Al dente
TechniquePasta or vegetables cooked until tender but still firm to the bite. Italian for "to the tooth".
B
Bain-marie
EquipmentA bath of hot water that a dish sits in, so it cooks or stays warm gently and evenly.
See also: Temper
Baste
TechniqueTo spoon or brush fat or pan juices over food while it cooks, adding flavour and helping it brown.

TechniqueTo cook briefly, then cool quickly in iced water. Sets colour, loosens skins and part-cooks vegetables.
See also: Boil
Braise
TechniqueTo brown food, then cook it slowly in a covered pot with a little liquid.
C
Caramelise
ScienceTo cook sugar until it browns and develops deep, nutty flavour.
See also: Maillard reaction
Chiffonade
Knife cutLeafy herbs or greens stacked, rolled tightly and sliced into thin ribbons.
D
E
Emulsion
ScienceA smooth, stable mixture of two liquids that don't normally mix, such as oil and vinegar.
F
Fold
BakingTo combine a light, airy mixture with a heavier one using gentle sweeping turns, so the air stays in.
Fond
IngredientThe browned bits left on the bottom of a pan after searing. The base of a pan sauce.
See also: Deglaze
J
K
Knead
BakingTo work dough by pressing, folding and stretching it, which develops gluten and gives bread its structure.
See also: Proof
M
Maillard reaction
ScienceThe browning reaction between amino acids and sugars that gives seared, roasted and baked food its savoury flavour.
See also: Caramelise
Mise en place
TechniqueHaving every ingredient measured, cut and within reach before cooking starts.
P
R
Reduce
TechniqueTo simmer a liquid uncovered so water evaporates, thickening it and concentrating its flavour.
See also: Deglaze
Roux
IngredientFlour cooked in fat, used to thicken sauces, soups and stews.
S
Sauté
TechniqueTo cook quickly in a little fat over fairly high heat, keeping the food moving.
Simmer
TechniqueTo cook in liquid just below boiling, with small bubbles breaking the surface.
See also: Poach
Sweat
TechniqueTo cook vegetables gently in a little fat so they soften and release moisture without browning.
See also: Sauté
T
Temper
TechniqueTo raise the temperature of an ingredient gradually, such as eggs, or to heat and cool chocolate so it sets glossy.
See also: Bain-marie
Z
Zest
IngredientThe thin, coloured outer skin of citrus fruit; also, to remove it.
Often confused
Poach, simmer or boil?
All three cook food in liquid. The difference is the temperature, and you can read it from the bubbles. Ranges are approximate, at sea level.
The surface barely moves; a few bubbles cling to the pan. For eggs, fish and fruit.
Small bubbles break the surface steadily. For stocks, stews, sauces and beans.
Large bubbles roll constantly and stirring doesn't stop them. For pasta and blanching.
Common cooking term questions
- Sautéing cooks food quickly in a small amount of fat over medium-high heat, keeping it moving. Searing cooks at higher heat with minimal movement to form a deep brown crust via the Maillard reaction. Both are distinct from frying, which uses more fat.
- "Mise en place" is French for "put in place." It means having every ingredient measured, cut and within reach before cooking starts. Professional kitchens treat it as a discipline, not a suggestion. The Auguste Escoffier School has a good overview of why it matters.
- Poaching is 70–80 °C — the surface barely moves. CookTheGuideing is 85–95 °C — small steady bubbles break the surface. Boiling is 100 °C at sea level — a full rolling boil. Each is right for different foods. See the CookTheGuide and Poach entries, or the Serious Eats guide to cooking temperature.
- "Al dente" is Italian for "to the tooth." Pasta is al dente when it is tender but still has a slight firmness in the centre. The Barilla pasta guide recommends tasting 1–2 minutes before the packet time, then draining when a small white dot is just visible inside a cut piece.
- A roux is flour cooked in an equal weight of fat (butter, oil or lard) until the raw flour taste cooks out. It is the thickener behind béchamel, velouté, espagnole and their derivatives. Cooking it longer produces darker roux with nuttier flavour but less thickening power. King Arthur Baking covers the ratios in detail.
