If you have more pineapple than you can use right away you can freeze the rest for later. Freezing is a great way to store your excess pineapple, especially for use in frozen drinks and smoothies. This is a guide about freezing pineapple.
I peel the pineapples and cube or liquidize them. Add a table spoon of lemon juice and 1/2 cup sugar to the pineapple heat through till it comes to a boil. Cool. Store in the freezer and use for cakes, tarts, make jam or have it in my yogurt.
