Judith Cullen shares her recipe for Grape and olive mostarda

2 cups fresh grapes
1 cup black Kalamata olives, (stone in)
3 Tbsp balsamic vinegar
3 Tbsp olive oil
1 Tbsp freshly chopped thyme

Place all the ingredients in an oven-proof bowl and bake for 1 hour at 180degC, turning the fruit with a spoon often during cooking until they are soft and the grapes are juicy.

Serve this with my roasted turkey or chicken.

You can also eat it as a finger food, like a bowl of olives.

It can be served with a garlic-flavoured flatbread or pizza bread.
