It most certainly does not keep the pot from boiling over. I’ve had it happen plenty. Same with the “place a wooden spoon across the top of the pot to prevent boilover” trick. That does not work either.
I agree that the wooden spoon thing is horse shit. Never once seen it work. The oil in the water does work for me. Now I know that many things may affect this. If you crank your stove up to eleven, maybe nothing will help. Maybe your altitude will affect it in some way. I live at about 350m above sea level. What I can say for sure is that in a large pot of water, at a rolling boil on my stove, about 3 tablespoons of oil in the water and a full pack of pasta, my pot will not boil over, but it absolutely will if I don’t add the oil.
Oil in pasta water. Though it’s much much older than YouTube.
It changes the surface tension and keeps the pot from boiling over. Very useful if you’re also preparing a couple other dishes.
