Description
A finishing technique where cold butter and cheese emulsify with starchy risotto liquid to create creaminess without cream.
Technical
The sudden addition of cold butter (2-4°C) to hot risotto (60-70°C) creates a temporary temperature differential that slows butterfat crystallization while mechanical agitation disperses milkfat globules. Cheese proteins (casein) and rice starch form a stable network around fat droplets.
Culinary Significance
Transforms starchy rice broth into a velvety sauce while cooling the dish to ideal serving temperature (55-60°C).
