Recipes are written in a private language. “Sweat the onions” doesn't mean cook them sweaty — it means cook them slowly without browning. “Reduce by half” doesn't mean cut the heat in half — it means simmer until the liquid's volume has decreased by 50 %. “Salt to taste” doesn't mean “add salt” — it means “add salt incrementally and taste at each step until the dish is right.”
Most cooking-instruction language was developed in professional kitchens, refined for precision, and then handed down to home cooks without translation. Once you know the common terms, recipes start to read like instructions instead of riddles. This is a practical glossary — the 30 or so terms that show up most often in modern recipes and what they actually require you to do.
Heat and motion
Sweat
Cook in fat over low–medium-low heat without browning. Often used for onions, shallots, leeks, or carrots in the early phase of a soup or sauce. The goal is to soften and bring out sweetness without caramelizing. Visible signs: translucent, no colour. If anything starts browning, the heat is too high.
Sauté
Cook over medium-high to high heat in a small amount of fat, with frequent motion (the French sautermeans “to jump” — ingredients should jump when the pan is shaken). The goal is browning + cooking-through quickly. Sauté is the opposite of sweat.
Sear
Brown the outside of meat or fish in a very hot pan with a small amount of fat. Heat is high; pan must be preheated; movement is minimal — you want the surface in contact with the metal until it crusts. A proper sear takes 3–4 minutes per side on a steak; rushing it produces grey meat and no crust.
Deglaze
After searing, pour cold liquid (wine, stock, water) into the hot pan and scrape up the browned bits stuck to the bottom (the fond). Those bits are pure flavour; this step extracts them into your sauce. Deglazing is what makes pan sauces taste like restaurants.
Reduce
Simmer a liquid uncovered until it's thickened by evaporation. “Reduce by half” = wait until visually the volume is halved. “Reduce until syrupy” = wait until the liquid coats the back of a spoon. “Reduce to a glaze” = wait until almost no liquid remains and what's there is sticky and shiny.
Simmer
Cook in liquid that's hot enough to send up small bubbles intermittently from the bottom but not so hot it's rolling-boiling. Visually: lazy bubbles, gentle movement, surface barely disturbed. About 85–95 °C / 185–205 °F.
Boil / hard boil / rolling boil
100 °C / 212 °F at sea level. Vigorous, continuous bubbling that doesn't stop when you stir. Pasta water is a rolling boil. A “gentle boil” is between simmer and rolling boil — some bubbles, but not violent.
Poach
Cook in liquid that's below simmering — 70–85 °C / 160–185 °F. Visible heat shimmer, occasional tiny bubbles, but mostly still. Poaching is for delicate proteins (eggs, fish, chicken breast) that turn rubbery if exposed to higher heat.
Braise
Brown the protein, then cook it slowly in a small amount of liquid in a covered pot, usually in the oven at 150–180 °C / 300–350 °F. The liquid simmers, the steam stays in. Tough cuts (chuck, short rib, lamb shank) become tender over hours. The liquid becomes the sauce.
Fold
Combine two ingredients of different densities (whipped egg whites into batter, whipped cream into mousse) without deflating the lighter one. Use a spatula; cut down through the centre, sweep along the bottom, lift up over the top. Repeat, rotating the bowl, until just combined. Stirring will collapse the air; folding preserves it.
Cream
Beat softened butter and sugar together until pale, fluffy, and visibly increased in volume — usually 3–5 minutes in a stand mixer, longer by hand. The sugar crystals cut into the butter, creating tiny air pockets that leaven the batter. A “quickly creamed” mixture is undermixed; cookies and cakes from undermixed butter are dense and flat.
Cuts and shapes
Mince
Cut into very small pieces, around 1–3 mm. Garlic, ginger, fresh herbs, and shallots are typically minced. Easier with a sharp knife (see knife maintenance, simply).
Dice
Cut into uniform cubes. Small dice = ~5 mm; medium = ~10 mm; large= ~20 mm. Uniformity matters because uneven pieces cook unevenly — small pieces overcook while large pieces are still raw.
Chop / rough chop
Cut into pieces of roughly the indicated size, but uniformity is unimportant. Used for stocks, soups, anything that'll be blended or strained out. Faster than dicing.
Julienne
Long thin matchstick strips, ~3 mm × 3 mm × 5 cm. Carrots, peppers, ginger. Brunoise is julienne cross-cut into tiny dice (3 mm cubes).
Chiffonade
Stack leafy herbs (basil, mint, sage) flat, roll into a tight cylinder, slice across into thin ribbons. The presentation cut for fresh herbs over pasta or salads.
On the bias
Cut at an angle, usually 45 degrees, instead of straight across. Gives larger surface area for the size of the piece — useful for vegetables in stir-fry, scallions on top of a finished dish.
Doneness signals
Translucent
Onions / shallots / fennel are translucent when light passes through them — they look slightly glassy, less opaque than raw. The signal that they're cooked through but not yet browning.
Caramelized
Properly browned through the Maillard reaction. For onions, this means dark golden brown after 30–45 minutes of low heat. “Caramelized in 5 minutes” is always a lie — that's sautéed.
Until fragrant
Cook until the smell rises sharply — usually 30 seconds for garlic, 1 minute for spices. The point is to bloom the aromatic compounds in oil without burning the solids.
Al dente
Italian for “to the tooth.” For pasta, the centre still has a thin white line of uncooked starch when you bite a strand — about 1 minute before fully-cooked. The texture is firm rather than soft. Always cook pasta to al dente; it finishes in the sauce.
To the touch
For meat, you can judge doneness by pressing it — the firmer it is, the more cooked. Rare = like the muscle at the base of your thumb when relaxed; medium = the same muscle when you press your thumb to your middle finger; well-done = ring finger. Trust a thermometer instead.
Carryover cooking
Meat continues to cook after you remove it from heat — the residual heat keeps raising the internal temperature by 5–10 °F. Pull a steak at 130 °F and rest it, and it'll reach 135–140 °F (medium-rare) on the cutting board. Recipes accounting for this say “rest 10 minutes;” ones that don't produce overcooked meat.
Salt and seasoning
Season aggressively / season generously
Use more salt than feels comfortable, especially on meat and on pasta water. Pasta water should taste like sea water. Steak should be visibly coated. Most under-salted food is under-seasoned by 30–50 %.
To taste
Add incrementally and taste at each step. The first dose is rarely enough; under-salted food is the most common home-cooking failure. Trust your tongue, not the recipe.
Adjust seasoning
At the end of cooking, taste and add what's missing. The dish might need more salt, more acid (lemon, vinegar), more heat (chili), or more umami (soy sauce, fish sauce, Parmesan). The four-part diagnostic: salt, acid, heat, umami.
The bigger lesson
Recipe language is precise, just compressed. Once you can decode the verbs and the doneness signals, recipes stop being puzzles and become straightforward instructions. The next time you see “sweat the aromatics, deglaze with white wine, reduce by half, then simmer until the meat is fork-tender,” you'll know exactly what happens at each step — and you'll know what the recipe writer didn't say but assumed: pan size, heat level, approximate timing, what success looks like. That's reading like a chef.
