Pineapples Preserved

Ingredients

Directions

Prepare the pineapples

  1. Clean the pineapples without removing the rind or leaves.

  2. Place the whole pineapples in a large pot and cover with cold water.

  3. Boil until tender enough to pierce through to the core with a straw.

  4. Remove the pineapples from the pot and drain them.

  5. Once cool, remove the leaves and pare off the rind.

  6. Cut into round slices ½ inch thick, removing the core and leaving a small hole in each slice.

  7. Weigh the slices.

  8. Use 1 cup of sugar for each cup of fruit.

Layer with sugar

  1. Cover the bottom of a deep dish with a thick layer of sugar.

  2. Add a layer of pineapple slices.

  3. Repeat layering until all slices are used, finishing with sugar on top.

  4. Let stand for 24 hours.

Make the syrup and jar

  1. Drain the syrup and place the slices in wide jars.

  2. Boil the syrup until no scum rises.

  3. Strain the syrup.

  4. Pour the hot syrup over the pineapple and cover.

What each ingredient does

Pineapples
Provide the fruit that is cooked, sliced and preserved in sugar.
White sugar
Draws moisture out of the fruit and preserves it as a thick syrup.

The step that matters

Boil the syrup until no scum rises. Skimming off the scum as it rises removes impurities from the sugar syrup, so the preserve stays clear and keeps better.
