- Chop up the orange and lemon, leaving the peel on. Put all the ingredients in a saucepan and bring to the boil. Simmer for 1 hour with the lid on the pan (don’t evapourate off as this is really precious). Strain through a fine sieve and bottle.
- To use, take 1 measure of syrup to 2 measures of wine. Heat to just below boiling point and serve in glasses.
