• 500 g berries (such as blueberries, strawberries, blackberries or a combination of these)
• ¾ c sugar
• 2 tbsp berry liqueur (optional)
• 1 c thick plain yoghurt

Place all the ingredients except the yoghurt in a food processor and mix until smooth.  Add the yoghurt and process again.

Pour into a shallow metal container and freeze.  Chop the sorbet into chunks and process again (in small batches) until smooth.  Tip back into the container and refreeze.  This makes about four cups and is best served piled up in glass dishes or glasses.
