Is there a name for the partial dish where you simmer macaroni in milk for 30-60 minutes? It's called stuvade makaroner in Swedish:
The linked recipe (while I don't read Swedish, Google helps) is for what in the UK we'd call macaroni cheese ("macaroni and cheese" to Americans). It doesn't actually cook the macaroni in the milk, but in water: Translated excerpt:
Cook macaroni according to the instructions on the package.
Pour off the water in a colander and pour the macaroni back into the saucepan.
(then add the sauce and cheese)
In the UK we have a dessert called "creamed macaroni". It usually comes in cans. I've never heard of anybody actually making it from scratch. It's basically macaroni in a creamy sweet sauce. There must be a recipe somewhere. I don't know if the pasta is actually cooked in milk or water though.
And yes it is as horrible as it sounds IMHO. I tried it once, that was enough. Although somebody must buy it, otherwise it wouldn't exist.
