Everything You Ever Wondered About Dessert Custards

Dessert custards all share something in common: a silky texture and impossibly rich flavor. But what marks the difference between pot de crème and crème caramel, or pastry cream and pudding? The difference lies in four factors: the ratio of ingredients, the manner in which the custard is thickened, the method of cooking, and any additional components.

In custards, the proportion of eggs to sugar to dairy is critical, since texture and flavor hang in delicate balance. Eggs lend sturdiness, and the most opulent custard desserts contain only egg yolks. Sugar also affects texture: The more sugar in a custard, the less firm it will tend to be, and the longer it will take to set. And the amount of fat in your dairy, whether cream or milk, will affect the dessert’s level of richness.

Custard is set in one of three different ways: with eggs, starch, or gelatin. Crème brûlée, pots de crème, and flan are thickened with egg; in contrast, pastry cream and American-style cheesecake often employ cornstarch or flour. Gelatin is used to add a gel-like consistency to Bavarian cream and most mousse recipes.

All custards are set using low, gentle heat. However, they fall into one of two categories: stirred (cooked on the stovetop) or baked (set in a water bath in the oven). Crème anglaise, pastry cream, mousse, and pudding are stirred; flan, crème brûlée, and pots de crème are baked. Custards can also be served at a wide range of temperatures: Serve crème anglaise warm, and it’s a sauce; freeze it and it becomes ice cream.

More elaborate custard desserts involve additional components, such as toppings or coatings. Crème brûlée contains a layer of hard caramel on top, achieved by melting sugar with a blowtorch; crème caramel is coated in a layer of soft caramel before being turned out.

Crème anglaise is a stirred custard made with milk, sugar, and eggs (or sometimes gelatin).
