Sour-cream porridge cooked until butterfat separates and pools on top, topped with cinnamon sugar — Norway's wedding-and-funeral comfort.
Rømmegrøt is one of the oldest dishes in the Norwegian repertoire — a porridge made from cultured sour cream (rømme), boiled until the butterfat separates out and pools on top, then thickened with flour. The pooled fat is poured off and used as a finishing 'sauce'. Topped with cinnamon sugar, served at weddings, funerals, the Constitution Day (May 17), and the harvest. The skill lies in extracting the maximum butter — a good cook gets a deep golden pool an inch thick.
A pale yellow porridge thick as polenta, with a finger-deep pool of clear golden butter melted on top. Cinnamon sugar across the surface. Eat hot; a cold serving turns inedible-firm.
Boiling sour cream until the butterfat breaks free of the protein matrix is the trick — it's literally extracting clarified butter from sour cream. The flour added afterward thickens what's left of the milk-water portion into porridge.
Variations
Recipes vary by region: west-coast versions (such as Hardanger) tend to run thinner and pool more butter, while inland and central Norwegian versions are stiffer and use less — and it is often eaten alongside cured, dried meats (spekemat).

How it's made

- 112 min
Bring 500g full-fat cultured sour cream (35% fat minimum) to a simmer in a heavy pot. Cook over medium-low heat 20 min, stirring often — butterfat will start separating and pooling on top.
Watch outWatch for the golden butterfat beading up and pooling on the surface — that separation is the whole point; keep it at a bare simmer so it renders cleanly.
- 212 min
Tilt the pot; carefully spoon off the clear golden butter into a bowl — you should get 4-6 tbsp. Set aside.
Watch outSpoon off only the clear golden fat, tilting the pot — take any of the white milky layer under it and your porridge goes greasy.
- 312 min
Whisk 100g flour into the pot. Cook 5 min over low heat. Slowly whisk in 500ml whole milk until smooth.
- 412 min
Simmer 10 minutes more, stirring, until thick like polenta. Salt to taste.
Watch outCook until it mounds on the spoon and drops in thick sheets like polenta — thin porridge means it needs a few more minutes.

Ladle into bowls. Pour the reserved golden butter over the top in a shallow pool. Dust with cinnamon-sugar (2 tbsp sugar + 1 tsp cinnamon). Eat hot.
