500g caster sugar
3 tbsp red wine vinegar
How to make Raspberry cordial
. Put the raspberries in a pan with the sugar and vinegar. Mash over a low heat for 10 mins until smooth and syrupy.
. Rub through a sieve into a clean pan.
. Tip the seeds from the sieve into a bowl and stir in 300ml water, then sieve again to remove the last of the pulp from seeds.
. Pour the liquid into the pan with the sieved pulp, stir well and boil for 1 min. Pour into small sterilised bottles and seal.
. The cordial will keep unopened for a few months. Once opened, store in the fridge.
