Strawberry-Pineapple Marmalade

A Tropical Three-Fruit Marmalade for the Pantry

This marmalade breaks the orange-only mold and brings together three fruits in one jar. Sweet pineapple, bright strawberries, and tangy orange pulp share the pot, with grated orange zest tying the whole thing together with a hint of citrus oil.

Staging the fruit matters. The pineapple, orange pulp, and zest go in first with the sugar to release pectin and concentrate during a hard 15-minute boil. Strawberries hold their bright color and shape better, so they go in second and cook just long enough to break down without turning to baby food.

The set comes from natural pectin in the orange and the pineapple’s acidity rather than commercial pectin. That makes for a softer, looser preserve with chunks of fruit suspended in syrup, more relish-leaning than a stiff jelly.

Pro Tips

• Use ripe but firm strawberries. Overripe berries break down too quickly and turn the marmalade syrupy and seedy.
• Stir frequently once the strawberries go in. The pectin-rich mixture sticks fast at the bottom and will scorch in seconds if neglected.
• Test the set on a chilled plate. A spoonful that wrinkles when nudged is ready; runny means more boiling.
• Process the jars in a water bath for the full 10 minutes. This is how you get a shelf-stable seal and prevent mold.

Variations

• Add a vanilla bean or a tablespoon of grated fresh ginger to the pot for a spice-warm preserve.
• Swap out an orange for a Meyer lemon for a brighter, more floral marmalade.
• Stir in 2 tablespoons of rum or Grand Marnier off the heat at the end for a boozy adult version.
