You may still be in time to find seville oranges on the market or in the shops. These have a somewhat more bitter taste than the usual ones available and are traditionally used for making marmalade. They have a very short season, but it is well worth trying to get hold of them.
If you are new to making marmalade, do have a go. There are plenty of good recipes available – I use one in the Jam, Preserves and Chutney book in a WI series – but there was actually one, which was very similar, on the net of oranges.
If you miss the seville oranges, don’t despair, why not ring the changes – you can make marmalade from a range of citrus fruits. You never know – yours might be a winner!
