What each ingredient does

Pineapple
Forms the fruit that is packed and preserved in the syrup.
White sugar
Sweetens the syrup and helps preserve the fruit's texture and flavor.
Water
Dissolves the sugar to form the syrup that covers the fruit.

The step that matters

Sealing the hot cans immediately. Filling and sealing while the cans and contents are hot creates a vacuum as they cool, which helps keep air out and the fruit safely preserved. Delaying the seal lets air and microbes in, risking spoilage.
