Plastic Petri Dishes Directions
No Pour MethodThere are many heat resistant containers that can withstand being pressure cooked, but plastic petri dishes are not one of them. You could use glass or pyrex petri dishes, baby food jars, or you could use any food grade plastic container that is made to heat food in the microwave. Surprisingly, these containers will withstand being pressure cooked. Most plastic containers have a rating symbol on the bottom. It is a triangle with a number in it. If this number in the triangle is 5, then it is heat resistant, also called pp5. If you look around at things, probably in your cupboard or at the store (tupperware,) you will start to notice this pp5 symbol. I myself like to use 8 oz deli dishes. The type you get your macaroni salad in from the local grocery store. You can usually find these at a restaurant supply store or online.
