Today I made my annual ten jars of Seville Orange Marmalade.
A simple process and a delicious result - so much more tangy than anything available in the shops.
Apparently ready-made marmalade sales in the UK are declining, but sales of fresh Seville bitter oranges are going up. They are still widely available here (imported from Spain) but only for about three weeks in January.
