2 very ripe bananas, peeled and thinly sliced
250 grams frozen mixed berries
250 grams crème fraîche
3 tablespoons maple syrup or honey
1 teaspoon vanilla extract
finely grated zest of ½ an orange
1-2 tablespoons orange or berry liqueur, optional
Place the banana slices in a single layer on a plastic wrap-lined tray and freeze.
Put all the ingredients in a food processor and blend until thick, creamy and smooth, scraping down the sides of the bowl several times to help break up the frozen fruit. Transfer to a freezer-proof container, cover and freeze for 2 hours if possible. You can eat it immediately but it will be very soft. The ice cream is best served the day it is made.
To serve: Scoop the ice cream into chilled glasses and top with yoghurt and berries.
Sour cream can be used in place of the crème fraîche if desired.
