World cuisines, sauces, techniques, and etiquette
Base
Butter + flour (roux) cooked until pale, then milk whisked in.
Key derivatives
Mornay (+ cheese), Soubise (+ onion purée), Nantua (+ crayfish butter), cream sauce.
Used in
Lasagne, moussaka, croque monsieur, cauliflower cheese, gratins, pasta bakes.
The roux is the key skill: equal parts butter and flour by weight, cooked over medium heat until it smells nutty but hasn't coloured (white roux). Then add milk gradually, whisking constantly to prevent lumps. Season with nutmeg. The ratio: ~50g butter + 50g flour per 500ml milk for a medium sauce.
Base
Blond roux (slightly coloured) + white stock (veal, chicken, or fish).
Key derivatives
Allemande (+ egg yolk/cream), Suprême (+ chicken velouté + cream), Vin Blanc (fish velouté + white wine).
Used in
Chicken dishes, fish dishes, vol-au-vents, creamy soups as a base.
The difference from béchamel: stock instead of milk gives a deeper, more savoury flavour. The blond roux (cooked a few minutes longer than white) adds a subtle nutty note. Velouté means "velvety" — the sauce should be smooth and silky, coating the back of a spoon.
Base
Dark (brown) roux + rich brown veal stock + mirepoix (carrot, onion, celery) + tomato purée. Slow-cooked, skimmed repeatedly.
Key derivatives
Demi-glace (espagnole reduced 50% + equal veal stock), Bordelaise (demi-glace + red wine + shallots + bone marrow), Chasseur, Robert, Madeira.
Used in
Rich meat dishes, stews, braised meats, classic French bistro sauces.
The most labour-intensive mother sauce — traditionally takes 2 days. The brown roux (cooked until deep brown) and reduction of rich bone stock creates extraordinary depth of flavour. Demi-glace is its most important derivative — the backbone of classical French restaurant cooking. When a sauce is described as "reduced to a glaze," this is the direction.
Base
Pork fat (or butter) + mirepoix + tomatoes + stock. The classical version uses salt pork and veal stock — more complex than Italian tomato sauce.
Key derivatives
Creole, Portuguese, Provençale. Also forms the base for pizza and pasta sauces in adapted form.
Used in
Braised meats, stuffed vegetables, eggs (shakshuka-style), pasta (simplified version).
Not to be confused with simple Italian pomodoro. The French classical sauce tomat is richer and more complex — includes roux, salt pork, and long cooking. The tomato arrived in France via Spain in the 16th century; Escoffier elevated it to mother sauce status. The modern kitchen often uses simplified tomato sauce as this base.
Base
Clarified butter whisked into egg yolks over gentle heat, with lemon juice or white wine vinegar. An emulsion — fat suspended in water by lecithin from egg yolks.
Key derivatives
Béarnaise (+ tarragon + shallots — classic with steak), Choron (béarnaise + tomato), Foyot (béarnaise + meat glaze), Maltaise (+ blood orange).
Used in
Eggs Benedict, asparagus, fish, vegetables. Béarnaise with steak is one of the great pairings.
The most technically demanding mother sauce — the emulsion can "break" (separate into greasy butter and watery eggs) if too hot or stirred too fast. Temperature control is everything: the bowl should be over barely simmering water, not boiling (below 65°C). If it breaks, whisking in a cold tablespoon of water or starting a new yolk in a clean bowl and slowly incorporating the broken sauce can rescue it.
Sofrito (Spain, Latin America)
The Mediterranean base
Onion + garlic + tomato + pepper slow-cooked in olive oil until deeply reduced and sweet. The foundation of Spanish, Italian (soffritto), and Latin American cooking. Nearly every savoury dish in these traditions starts here.
Mirepoix (France) / holy trinity (Cajun)
Aromatic vegetable base
Mirepoix: 2 parts onion, 1 part carrot, 1 part celery — the classical French start for stocks, soups, and braises. Cajun holy trinity: onion, celery, green bell pepper. Italian soffritto: onion, carrot, celery. Different ratios, same principle.
Dashi (Japan)
Umami broth base
Kombu (dried kelp) + katsuobushi (bonito flakes) steeped in water. The foundation of Japanese cooking — miso soup, ramen broth, noodle dipping sauces, nimono (simmered dishes). Ready in 20 minutes; defines a cuisine's flavour entirely.
Mole (Mexico)
Complex chile-based sauce
Dried chiles + chocolate + spices + nuts + seeds + tomatoes + charred ingredients — sometimes 30+ components. Mole negro from Oaxaca takes days to make. One of the world's most complex sauces and a cultural symbol. The chocolate does not make it sweet — it adds depth and colour.
Curry base (South Asia)
Onion + ginger + garlic + spice
The "masala base": slowly fried onion (often 30+ minutes until deep brown), then ginger-garlic paste, then tomatoes, then spice mix. The caramelised onion creates body and sweetness. This base is the foundation of most Indian subcontinent cooking — the specific spice blend varies enormously by region and dish.
XO sauce (Hong Kong)
Ultra-umami condiment
Dried scallops + dried shrimp + Jinhua ham + chilli + garlic + shallots. Created in Hong Kong in the 1980s, now a luxury condiment worldwide. XO refers to XO cognac — a branding exercise implying luxury. Intensely savoury and complex. Used as a finishing sauce, stir-fry base, or condiment.
Salt is not just seasoning — it's chemistry
Salt at every stage
Salting pasta water (should taste "like the sea") seasons the pasta from within — impossible to fix at the table. Salting meat before cooking draws moisture out then back in (dry brining). Salt suppresses bitterness, enhances sweetness, and amplifies all other flavours. Under-salted food always tastes flat, regardless of how good the ingredients are.
Fat carries flavour
Most flavour compounds are fat-soluble
Spices, herbs, and aromatics release their flavour into fat, not water. Frying whole spices in oil before adding other ingredients "blooms" them — releasing 10× more flavour. This is why low-fat cooking often tastes bland: the fat was doing flavour work, not just adding calories.
High heat for the Maillard reaction, low heat for tenderness
The two-temperature rule
Sear at high heat (180°C+) for flavour and colour via Maillard. Then low heat (slow roast, braise) for tenderness — collagen breaks down to gelatin at ~70–80°C over time. Trying to achieve both simultaneously is why many home cooks overcook the outside while achieving tenderness — sous vide cooking solves this by separating the two steps entirely.
Acid balances richness
The chef's secret weapon
A squeeze of lemon or splash of vinegar at the end of cooking is what separates restaurant food from home food in many cases. Acid brightens flavours, cuts through fat and richness, and makes other flavours more perceptible. If a dish tastes flat or "too heavy," it usually needs acid, not more salt.
Don't crowd the pan
Steaming vs searing
Meat or vegetables in a crowded pan release moisture that can't evaporate — they steam rather than sear, producing grey, soft food instead of browned and flavourful. Use a large hot pan with space between pieces, in batches if necessary. The pan must be hot enough that the food sizzles immediately on contact.
Taste constantly and adjust
Cooking is not following instructions
Recipes are guidelines, not laws. Ingredients vary (some lemons are more acidic, some tomatoes sweeter). The habit of tasting at every stage and asking "what does this need?" is what distinguishes a good cook from someone who follows recipes. Usually the answer is: more salt, more acid, or more cooking time.
1. You're making a béchamel but it has lumps. What went wrong, and how do you fix it?
2. What is the Maillard reaction, and why is it NOT the same as caramelisation?
3. You're at a fine dining restaurant. After your main course, you need to visit the bathroom. Where do you put your napkin, and what do you signal with your cutlery?
4. Why does restaurant pasta taste better than most home pasta, even using the same ingredients?
5. What is the difference between Japanese ramen, pho, and Chinese noodle soups — what defines each?
