In heating frozen foods in sealed pouches in a microwaves, why do you first poke holes in the pouch?
To prevent the steam pressure from bursting open the pouch
To allow the heat to get into the food through the hole
To allow the microwaves to get into the food through the holes
To allow the aroma of the food to come out through the holes
To prevent the steam pressure from bursting open the pouch
Anything in a tight skin or shell can explode in a microwave because the water inside can expand and burst through. It is for this very reason that before microwaving, the skin of potatoes should be pricked, winter squash and similar vegetables should be cut in half, eggs should be taken out of shells and holes should be poked in the plastic wrap or sealed pouches of frozen packaged foods.
