Whip

Beat air into cream or eggs until light, billowy, and voluminous

Whipping beats air into cream, egg whites, or eggs until they expand into soft, stable foam. It's what gives whipped cream, meringue, and mousse their lift. Keep cream cold and your bowl spotless for whites — fat or yolk traces will stop a meringue from taking.

Whipping beats air into a liquid until it traps thousands of bubbles and expands into a stable foam. With cream, the fat globules partly coalesce around the air, building structure that holds a peak; with egg whites, unfolding proteins form films around the bubbles, the foundation of meringue, soufflé, and angel cake. Success hinges on cleanliness and temperature: cream wants to be cold, egg whites want a spotlessly grease-free bowl. Stop at the right stage — soft, firm, or stiff peaks — because a few strokes too many turns cream to butter and whites to a grainy, weeping wreck.

Difficulty: Easy

Types & varieties

Whipped cream

Cold cream beaten with a little sugar to soft or firm peaks for topping and folding.

Meringue

Egg whites whipped with sugar into glossy, stable peaks for pavlova, topping, and macarons.

Whole-egg foam (genoise)

Whole eggs and sugar beaten warm into a thick ribbon to leaven sponge cakes.

Sabayon / zabaglione

Yolks and sugar whipped over gentle heat into a warm, airy foam.

How to do it

1
Chill or prep your gear
For cream, chill the bowl and beaters. For whites, make sure the bowl and whisk are perfectly clean and grease-free.
2
Start slow
Begin beating at moderate speed to break the liquid up and start building small, even bubbles.
3
Build volume
Increase speed as it foams. For whites, add sugar gradually once they turn frothy to build a stable, glossy structure.
4
Watch the peaks
Lift the whisk and read the peak — soft folds over, firm holds a gentle curl, stiff stands sharp and upright.
5
Stop at the target
Pull the moment you reach the stage you need; whipping is fast to overshoot at the end.
6
Use promptly
Fold or pipe whipped cream and whites quickly before the foam begins to weep and deflate.

The science

Whipping introduces air and stabilizes it. In cream, agitation knocks the protective membranes off fat globules so they partly clump together, forming a fat network that braces the air bubbles — which is also why over-whipping continues into butter. In egg whites, beating unfolds the proteins, which then bond into elastic films around each bubble; sugar dissolves into the water between bubbles, thickening it and making the foam more stable and glossy.

Common mistakes

Foams are unforgiving of small errors.

Any trace of yolk or fat in egg whites prevents them from whipping fully.
Warm cream won't whip — keep it cold and consider chilling the bowl.
Adding sugar to whites too early slows the foam and makes it dense.
Walking away at the end — both cream and whites overshoot in seconds.

Tips & pitfalls

A copper or stainless bowl helps whites; plastic clings to grease and resists clean whipping.
Cream of tartar or a drop of lemon juice stabilizes egg-white foam.
Slightly underwhip cream you plan to fold — folding firms it further.
Wipe the bowl with a little vinegar or lemon to strip any grease before whipping whites.
If you overshoot cream toward butter, a splash of fresh cream can sometimes loosen it back.
