LOADED WITH FOOD
- Use a spoon to put the jam into the jar while it's still "hot", fill the opening of the jar and close the lid with some slack, not tight.
- Put the jar with the jam in the pot, pour hot water to about 1/3 of the height of the jar body, cover the pot and let it boil. After 5 minutes of heating, put on rubber gloves to remove the jar, then twist the lid tightly to remove the expanding air.
