what if milk had pulp

Milk skin refers to a sticky film of protein that forms on top of milk and milk-containing liquids (such as hot chocolate and some soups). It is caused by the denaturation of proteins such as casein.

When milk is boiled, soluble milk proteins are denatured and then aggregate and form a sticky film across the top of the liquid, which then dries by evaporation.

In Nepal this skin is referred to as turr and many people enjoy consuming the skin along with the milk.
