Custards, creams & meringues
crème anglaise
crème anglaise · A classical French dessert sauce — a pouring custard made by suspending egg yolks in scalded milk, thickened by controlled coagulation of proteins without added starch. The defining characteristic is a fluid, silky consistency that coats the back of a spoon. Used as a sauce, a base for other desserts, or churned into ice cream.
The formula
1 L milk : 100–125 g sugar : 6–7 yolks
For a richer sauce, substitute up to 200 ml of the milk with heavy cream (reduce milk to 800 ml). Classic minimum is 6 yolks per liter; more yolks produce a thicker, more luxurious result. Yields approximately 1.0–1.1 kg finished sauce per liter of milk. Example: 500 ml milk + 60 g sugar + 3 yolks yields ~600 g sauce.
Identity
- Contains egg yolks as the sole thickener — no starch, no gelatin, no flour
- Reaches precisely 82–85 °C (nappe stage) — never boiled or overheated
- Fluid enough to pour at room temperature; coats a spoon without being stiff
- Vanilla bean is the canonical and dominant flavor
- Tempered into yolks slowly to avoid scrambling, then cooked gently with constant stirring
Ingredients
| Liquid | whole milk (3.5–3.8 % fat) | Full‑fat milk is non‑negotiable. Skim or low‑fat produces a thin, watery result. |
| Binder | egg yolks (60–65 g each) | 6–7 yolks per liter of milk. The sole thickening agent; proteins coagulate to form the custard structure. |
| Sweetener | granulated sugar | 100–125 g per liter. More sugar produces a sweeter, slightly more tender custard; less produces a more neutral, richer result. |
| Flavor | vanilla bean (1 pod per liter) | Split and infused in the hot milk. Madagascan or Mexican bourbon varieties are classical. Vanilla extract (1 tsp) is acceptable but produces a less aromatic result. |
| Liquid | heavy cream (optional, for richness) | Up to 200 ml may replace an equal amount of milk for a thicker, more luxurious sauce. Classic versions often use milk only. |
Method
- 1Combine milk, split vanilla pod (and seeds scraped), and half the sugar in a heavy saucepan. Heat over medium, stirring occasionally, until it just begins to steam and small bubbles form at the edges — do not boil.Scalding extracts maximum vanilla flavor and dissolves sugar before the yolks are introduced. Boiling drives off liquid and risks scorching.
- 2In a separate bowl, whisk yolks and remaining sugar vigorously until the mixture is pale, falls in a thick ribbon, and the sugar is fully dissolved.Dissolved sugar prevents graininess. Pale yolks have more air incorporated, which helps the sauce hold together during cooking. Dissolution also raises the yolk's coagulation temperature, buying time.
- 3Slowly pour the hot milk into the yolks in a thin, steady stream while whisking constantly.This is tempering — raising the yolk temperature gradually to ~60–65 °C before they hit the pan, preventing immediate protein coagulation and scrambling.
- 4Return the entire mixture to the clean saucepan. Cook over very low heat (or in a bain‑marie), stirring continuously with a wooden spoon or heatproof spatula in long, steady strokes along the bottom and sides.Constant motion ensures even heat distribution and prevents the proteins near the pan surface from over‑coagulating. The bottom is always the hottest zone.
- 5Cook until the mixture coats the back of a spoon (nappe stage), reaching 82–85 °C on an instant‑read thermometer. Remove from heat immediately.82–85 °C is the threshold where yolk proteins coagulate enough to thicken the sauce but before they tighten into curds. This is the precise window; overshooting produces a grainy, scrambled texture.
- 6Strain through a fine‑mesh sieve into a clean bowl. Press a sheet of plastic wrap directly onto the surface to prevent a skin forming. Cool in an ice bath to room temperature, then refrigerate.Straining removes any vanilla pod fragments and any prematurely coagulated yolk bits. Plastic wrap contact prevents skin formation caused by oxidation. Ice‑bath cooling halts residual cooking immediately.
Techniques that matter
tempering
Gradually raising yolk temperature before adding them to heat prevents irreversible coagulation. The slower and more consistent the pour, the smoother the result.
nappe test and thermometer monitoring
The nappe test (coats a spoon) is the classical indicator; a thermometer removes guesswork. 82–85 °C is the specific target for egg‑yolk coagulation in dairy.
bain‑marie cooking
Using a water bath insulates the custard from direct heat spikes, providing exceptional control — critical when cooking close to the scrambling threshold.
Variations & derivatives
crème anglaise au caféFrance
Infuse 15–20 g finely ground coffee in the hot milk for 5 minutes before straining. Coffee amplifies the richness of the yolks.
crème anglaise au chocolatFrance
Pour 150 g warm, finely chopped dark chocolate (70 % cacao) into finished sauce and stir until glossy and fluid. Do not cook chocolate in the custard.
crème anglaise à la noisetteFrance
Toast blanched hazelnuts, grind to paste, infuse in hot milk, then strain. Classic Piedmontese flavoring.
crème anglaise au caramelFrance
Prepare a dry caramel, deglaze with cold milk, reduce slightly, then proceed with the standard recipe using this caramelized milk.
crème pâtissièreFrance
Not a direct variation but a thickened derivative: add 40–50 g cornstarch (per liter) cooked into the tempered mixture. Used as a filling.

Substitutions
- heavy cream → additional whole milk — Cream adds richness and body. Replacing with milk produces a lighter, more austere sauce that still technically works but lacks the luxurious mouthfeel.changes result
- vanilla bean → 1 tsp pure vanilla extract — Extract works but lacks the aromatic depth of a scraped, infused bean. Add after cooking to preserve volatile compounds.
- egg yolks → whole eggs — Substituting whole eggs reduces richness and thickness. Use 4 whole eggs + 2 additional yolks per liter instead. Result is thinner and less luxurious.changes result
Troubleshooting
Grainy, curdled texture with visible white protein clumps
Yolks were heated above 85–90 °C, causing proteins to tighten and curdle. The pan was too hot or heat was applied unevenly. → Strain immediately through fine mesh. If severe, transfer to a blender and process on low speed until smooth. Never reheat once cooled. Going forward, use a thermometer strictly and cook over lower heat or in a bain‑marie.
Thin, watery sauce that won't coat a spoon
Too few yolks used; or sauce was removed from heat before reaching nappe stage; or yolks were poorly incorporated during tempering. → Return strained sauce to a clean pan. Whisk in 1–2 additional yolks tempered with a spoonful of warm sauce, then cook gently to nappe again.
Sauce broke (separation, oily appearance, or visible liquid pooling)
Heat shock or excessive stirring after cooking can destabilize the yolk‑milk emulsion. Older yolks with weaker vitelline membranes are more prone to breaking. → For a broken sauce, transfer to a blender and process while slowly drizzling in a tablespoon of cold milk or cream. This can re‑emulsify if the break is minor. Prevention: cool the sauce immediately over ice and never stir once cooled.
Strong eggy or sulfurous flavor
Sauce held too long at 70–80 °C (the temperature range where egg proteins release hydrogen sulfide, especially from older yolks reacting with iron in the milk). Overcooked or over‑held. → This flavor dissipates slightly with cold storage but cannot be corrected in finished sauce. Use fresher yolks (within 2 weeks of pack date) and avoid holding at mid‑range temperatures.
