I – try to – make my own homemade yogurt as much as possible. I have to boil the milk first, in order to do that. However, since I neither have the patience nor the attention span to keep an eye on the stove, the milk has a high risk to boil over. Spilled milk on a stove is pain to clean up so I use this trick to prevent it from boiling over.
I put the milk in the saucepan and turn the medium heat on. Then, I put a wooden spoon on the pan. I also set the stove timer and alarm as a second precaution. But the wooden spoon is my security valve.
Even if the milk boils and foams up, it does not spill over – as shown in the picture above.
