This isn't your typical idiot move of putting stuff in oil too fast it will never stop foaming and it is a very fine and fluffy foam.
One time I did have a big fluffy Mr Bubbles foam come over the top and get all over the stove top.
This sucks when you are hungry and cooking.
I have even experimented with foaming oil.
One is to have the food for awhile in the oil and it is a small foam as the I heat the oil up them more foam it produces.
I have tried all types of oil and they will all do it.
The one thing I know as fact is that if I cook oily fish in the oil it will most of the time but not all of the time ruin the oil for anything after that.
This can happen with the second fry of the oil.
This foaming oil phenomenon and economics has turned me completely away from buying a deep fat fryer.
Most of the time I pan fry anyway.
When I do get on a frying binge I just use a small thick kettle and put a lid on it when not in use.
Sometimes I will have two going at the same time on the stove.
