What each ingredient does

Vegetable marrow
Forms the bulk of the marmalade and turns tender as it cooks in the syrup.
Sugar
Sweetens the dish and draws liquid out of the marrow, helping preserve it.
Lemon
Juice adds acidity and the grated rind adds a bright citrus aroma.

The step that matters

Boiling the marrow in the syrup for one hour. A steady boil in the sugar syrup concentrates the liquid and turns the slices clear and firm. Boiling too hard or too long can break the thin slices down into mush.
