What each ingredient does

Vegetable marrow
Forms the bulk of the marmalade and becomes tender and translucent as it cooks in the syrup.
White sugar
Provides sweetness and, as the syrup thickens, preserves the marrow and gives the marmalade body.
Lemon juice
Adds acidity that brightens the sweetness and helps the marmalade set.
Lemon rind
Contributes aromatic citrus oils that flavour the syrup.

The step that matters

Boil the marrow gently. A hard, rolling boil can break the marrow into mush and scorch the concentrating sugar syrup. Gentle simmering keeps the pieces intact while the syrup slowly thickens and the sugar concentrates for preserving.
