What is the only milk that doesn curdle when boiled?
I know this just from experience and here is an excerpt that backs up my theory!! Skim milk will curdle when brought to a boil. Only 35% cream will not curdle when boiled. Usually, the soup recipe will say bring the soup to a simmer and add the milk just before serving. Another thing you can do is whisk one cup of cold milk into 2 tablespoons of flour and add this to the boiling soup. It will not curdle. I don’t know the proportions of your soup but if it calls for 2 cups of milk than mix into 4 tablespoons of flour etc…. I usually thicken my cream soups with some potatoes and add more veggies than called for. Permalink | www.chowhound.
