This traditional Seville orange marmalade is bright, gently bitter, and beautifully set with soft shreds suspended in glossy jelly. The flavour is bold and citrus-forward with a clean finish, just as a proper breakfast marmalade should be. It is a confident but manageable recipe for home cooks who enjoy a slow, careful process. Allow a little time, most of it hands-off, for soaking, simmering, and potting.
Ingredients
For the marmalade
- 1 kg Seville oranges
- 2 lemons
- 2.3 litres cold water
- 2 kg granulated sugar

How to Make Delia Smith Seville Orange Marmalade
- Prepare the fruit: Wash the oranges and lemons. Cut them in half, squeeze out the juice, and keep all pips and membranes. Slice the peel to your preferred thickness.
- Simmer the peel: Place peel, juices, and water into a large preserving pan. Tie the pips and membranes in muslin and add to the pan. Simmer gently for about 2 hours until the peel is completely soft.
- Add the sugar: Remove the muslin bag and squeeze well. Add the sugar to the pan and heat gently, stirring, until fully dissolved.
- Boil to setting point: Increase the heat and boil steadily. Test for a set using a chilled plate. When ready, the surface will wrinkle when pushed.
- Pot and cool: Let the marmalade stand for 10 minutes, then pour into warm sterilised jars. Seal and leave to cool completely.
Tips
How do I avoid tough peel?
Simmer the peel until truly soft before adding sugar. This step is essential and should not be rushed.
Why is my marmalade too runny?
It may not have reached setting point. Return it to the heat and boil again, testing frequently.
How fine should I slice the peel?
That is personal preference. Fine shreds give a more delicate texture, while thicker peel adds bite.
