Pineapple Marmalade

Ingredients

Directions

Prepare the pineapple

  1. Peel and grate the pineapple, saving all the juice.

  2. Cook the pineapple pulp for 30 minutes.

  3. Strain the cooked pulp through a colander.

Make the marmalade

  1. Return the strained pulp to the heat and boil, stirring constantly until it thickens.

  2. Weigh the pulp and juice, then add 1 pound of sugar for every pound of pineapple.

  3. Boil the mixture for another 30 minutes, testing for doneness by pushing your finger through a small amount taken out to cool.

What each ingredient does

Pineapple
Provides the fruit body, natural pectin and acidity that give the marmalade its flavor and set.
Sugar
Adds sweetness and, with boiling, thickens the mixture as it concentrates and sets.

The step that matters

Boil the mixture with sugar until it sets. Sugar and pectin only gel when enough water has evaporated and the sugar concentration is high. Stopping too early leaves a runny marmalade, while overcooking can make it stiff or caramelize. Testing a cooled spoonful shows whether it has reached the setting point.
