Rømmegrøt is a traditional porridge originating from Norway. Although there are several variations, it's usually made with a combination of sour cream, flour, full-fat milk, and salt. It's recommended to use homemade or high-fat sour cream, with no gelatin or stabilizers.

The sour cream is shortly simmered and the flour is then sifted into the pot. The combination is simmered until the butterfat begins to separate, and the fat is skimmed off of the surface. The mixture is mixed with boiling milk and the porridge is whisked until smooth, simmered for a bit more and seasoned with salt.

Rømmegrøt is typically served with sugar, cinnamon, and the remaining fat. In the past, this porridge was commonly enjoyed with dried meats on festive days.
