Orange Marmalade
Ingredients
Directions
Prepare the fruit
Use equal weight of oranges and sugar.
Grate the yellow peel off half the oranges.
Peel the yellow peel off the other half of the oranges and cut into small strips.
Boil the cut peel in three different waters until tender.
After removing all the tough white skin, cut the pulp into small pieces.
Place the pulp in a colander and let the juice run through onto the sugar.
Cook and set
Boil the sugar for about ten minutes, adding a little water if necessary, and skim well.
Add the pulp and grated peel to the sugar.
After boiling for six minutes, add the cut peel and boil for fifteen minutes.
If the oranges are very sweet, add the juice of two or three lemons or grape fruit before cooking.
Transfer the mixture into jelly glasses.

What each ingredient does
- Oranges (in the method)
- Peel and pulp supply the bitter flavour, aroma and pectin that help the marmalade set.
- Sugar (in the method)
- Sweetens and, with the fruit's pectin and acid, helps the mixture thicken and set.
- Lemons
- Add acidity that balances sweetness and supports pectin setting, if the oranges are very sweet.
The step that matters
Cooking the peel until tender before adding it. Peel strips must soften fully in water before they go into the sugar, because tough peel stays chewy and will not soften once the sugar syrup thickens.
