Sometimes I will cook things that "foam" up when boiled (milk, steel cut oatmeal) and if I'm right next to the stove, I blow on the top of the pot and the foam subsides no problem. However, it seems inevitable that I'll step away from the stove to get something from the fridge and BOOM the foam goes up and over and squelches my gas stovetop and makes a mess (especially with the oatmeal!).
Any suggestions for how to get the foam to stay down without me having to stand there blowing on it?
(I realize I could use a really big pot to keep all foam inside, but I live in a small space and don't even have many big pots - but I will resort to this if it's the only way. I just thought there might be some trick or tip that I don't know!)
