Whole Pineapple

Ingredients

1 whole pineapple
hot 35-degree syrup (sugar syrup)

Directions

Prepare

Pare, core, and remove all eyes from the pineapple.
Place the pineapple in sanitary cans.

Fill and seal

Fill the cans with hot 35-degree syrup.
Seal the cans and process: No. 2 cans for 12 minutes at 240°F (115°C), No. 3 cans for 15 minutes at 240°F (115°C).
If sanitary cans are unavailable, use ordinary cans, cover the top with parchment paper, snap on the lid, and float in hot water quickly. Remove the parchment paper through the cap hole and proceed as above.

What each ingredient does

Pineapple: Provides the fruit that is packed whole and cooked in the syrup.
Sugar syrup: Sweetens the fruit and fills the cans, carrying flavor and moisture through processing.

The step that matters

Processing the sealed cans at 240°F (115°C) for the stated time. Heat must reach the centre of the cans for the full time to destroy spoilage microbes. Shorter times or lower temperatures risk an unsafe, spoiled pack, while the sealed headspace and syrup carry heat through the fruit.
