Step 1

Peel the pineapple and grate the flesh -- you should end up with about 2 cups. Put the pineapple and water in a small saucepan and cook over medium-low heat until the pineapple is soft, about 35 minutes.

Step 2

Add the sugar and lime juice and stir to combine. Cook until the mixture has thickened, about 45 to 60 minutes. Spoon the jam into a 16-ounce jar with a tight-fitting lid. Store it in the refrigerator for up to 3 months.
