Postre de Natas

A slow, patient Colombian dessert built from the skins (natas) that form on simmering milk, layered with a sweet egg-yolk syrup, raisins and a hint of rum or cinnamon. The result is a rich, slightly chewy milk pudding that tastes of pure caramelized cream.

Rum

Born in the Andean highlands around Bogotá, postre de natas comes from a thrifty old habit — back when families boiled their own unpasteurized milk, the skins that formed on top were carefully saved rather than discarded. Layered with syrup and sugar, those humble milk skins became a cherished weekend dessert served after ajiaco or a family asado.

Spoon into it and you find soft, custardy folds of milk skin steeped in caramel-sweet syrup, punctuated by plump raisins. It is dense, creamy and unapologetically rich, with a warm whisper of cinnamon and rum on the finish.

Heating milk evaporates surface water and concentrates proteins and fat into a skin (nata) as the casein and whey denature; collecting many of these skins and binding them with an egg-yolk syrup creates a uniquely dense, layered custard.

How it's made

8 steps · 15 min

1
10 min
Pour whole milk into a wide pot and bring to a gentle simmer over low heat.
2
5 min
As a skin forms on the surface, lift it off carefully and set aside in a bowl.
Watch out
Wait for a wrinkled skin to form on the surface, then lift it off whole and gently — the more intact skins you save, the denser and more layered the custard.
3
60 min
Repeat patiently for about an hour until no more skins form.
4
10 min
In a separate pan, dissolve sugar in a little milk and simmer into a light syrup.
5
12 min
Whisk egg yolks, temper with the warm syrup, and cook gently until slightly thickened.
Watch out
Temper the yolks by dribbling the warm syrup in slowly while whisking, then cook just until it coats a spoon — rush it and the yolks curdle into lumps.
6
5 min
Fold the reserved milk skins into the syrup with raisins and a splash of rum.
7
120 min
Pour into a serving dish and chill for at least 2 hours to set.

3 min
Dust with ground cinnamon before serving cold.
