Step 1

Peel, core, and coarsely chop pineapple. Place pineapple in a food processor and pulse 2-3 times until it's very fine, but not completely pureed. (Alternately, start with canned crushed pineapple.)

Step 2

Place pineapple in a jam pot or deep saucepan.

Step 3

For every cup of crushed pineapple, add 1/2 to 2/3 cup sugar. A medium pineapple yields about 3 cups crushed pineapple and would require 1 1/2 to 2 cups sugar.

Step 4

Bring the mixture to a boil over high heat, stirring to prevent scorching. Cook on high for 25 to 30 minutes until the mixture thickens.

Step 5

Ladle into prepared jars leaving 1/4 inch headspace.

Step 6

If canning, process in a water bath canner for 10 minutes, adjusting for altitude.
