Soufflé Base (Béchamel to Egg)

3

Thick béchamel base — Stiff enough to hold a ribbon — roughly 15% roux (1.5× standard sauce roux) thinned to a heavy paste

2

Egg yolks — Beaten in one by one off the heat; typically 3–4 yolks per 250 g base

3

Egg whites — Whipped to firm (not stiff) peaks; typically 4–5 whites per 250 g base for good rise

Make a thick béchamel: melt 30 g butter, stir in 30 g flour, cook 1–2 minutes, then add 200 ml hot milk gradually, stirring until very thick and smooth. Remove from heat. Beat in egg yolks one at a time, stirring vigorously after each so the heat does not scramble them. Fold in the main flavouring (grated cheese, chocolate, vegetable purée). Whip whites with a pinch of cream of tartar or salt until they hold firm, glossy peaks but are not dry. Lighten the yolk base with one-quarter of the whites (stir vigorously to loosen), then fold in the remaining whites in two or three additions using a wide spatula — cut and fold, rotating the bowl, until just combined with a few white streaks remaining. Pour into a buttered, crumbed ramekin filled to three-quarters. Bake at 190–200 °C for 12–16 minutes (individual) or 25–35 minutes (large soufflé dish) without opening the oven door.

• The béchamel base must be warm (not piping hot, not cold) when yolks go in — ideally 50–60 °C — to avoid scrambling while still dissolving the yolk proteins.
• Egg whites must be free of any yolk or fat; even a trace prevents the proteins from forming a stable foam.
• Fold with the minimum number of strokes needed to lose visible white streaks; over-folding deflates the foam and the soufflé will be flat.
• A collar of buttered parchment tied around the ramekin lets the mixture rise above the rim without falling over the edge.
• The ratio of whites-to-base can be nudged toward more whites for a taller, drier soufflé or fewer whites for a denser, creamier one.

• Cheese soufflé (Soufflé au fromage)

  Add 80 g Gruyère + 20 g Parmesan per 250 g base; a pinch of cayenne is traditional

• Chocolate soufflé (dessert)

  Replace béchamel with a crème pâtissière base; melt 70% dark chocolate into the base at 20% weight; slightly fewer whites (ratio tips toward 2:3 whites to base) for a fudgier interior

• Spinach or vegetable soufflé

  Drain purée extremely well before folding in — excess moisture wets the whites and prevents rise; increase roux by 20% to compensate

• Two-stage soufflé (restaurant method)

  Base + yolks prepared hours ahead, whites folded and baked to order; base must be brought to room temperature before folding

• Soufflé glacé (frozen)

  No egg whites baked — instead Italian meringue is folded into whipped cream + flavoured base and frozen; served in the same ramekin but not cooked

• Béchamel (Roux to Milk)

  The parent sauce; soufflé base uses a stiffer version of the same formula

• Mornay Sauce (Béchamel to Cheese)

  A cheese-enriched béchamel; the same sauce flavoured with extra cheese is the classic soufflé base

• Crème Pâtissière (Milk to Egg to Starch)

  Alternative soufflé base used in dessert soufflés instead of béchamel
