I like to serve this yoghurt a little on the soft side rather than frozen solid. Remove it from the freezer to soften before serving and the berry flavour will really shine through.
400 grams mixed berries, use fresh or frozen, thawed with their juice
2/3 cup condensed milk
2 cups thick yoghurt, plain, sweetened or fruit
finely grated zest 1 large lime
Put the berries in a food processor and blend until smooth. Press through a sieve set over a bowl and discard the seeds. Add the condensed milk and mix until well combined. Add the yoghurt and lime zest and fold together. Tip into a metal dish, cover and freeze until half the mixture has frozen. Scrape into a food processor and blend until smooth. Tip back into the dish and freeze for at least 8 hours.
To serve: Scoop into bowls or glasses and serve with extra fresh berries if desired.
