Hull and slice strawberries. For each cup of fruit, sprinkle a tsp of caster sugar. Add 1/2 tsp vanilla extract (mine has seeds mixed in) and a tbsp of balsamic vinegar. Mix, then pop in the fridge for around an hour.
You might want to make sure you are alone before you take the strawberries out to eat. For starters, you don't want to share this. But more importantly, you will be left with a small quantity of vanilla and balsamic syrup once the strawberries are over. You don't want to let go of this one; not even a drop. Maybe the phrase lick the bowl clean comes to mind!
