Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Loaf sugar
- Draws water out of the marrow and preserves it, giving sweetness and a syrup that sets the preserve.
- Vegetable marrow
- Provides the bulk of the preserve, absorbing syrup and turning tender as it cooks.
- Lemons
- Add acidity that brightens the sweetness and helps the preserve set.
- Ginger
- Adds warm aroma and a gentle spicy flavour that carries through the preserve.
The step that matters
Skim the boiling mixture until clear. Impurities rising to the surface can cloud the syrup and spoil the flavour. Removing them as the mixture boils keeps the preserve clear and clean-tasting.
Swap the lemon
