Crème fraîche ice cream

Whisk together the milk, sugar, crème fraîche, lemon zest and vanilla. Set aside for 10 mins for the sugar to melt. Churn in an ice-cream machine, following manufacturer’s instructions, before freezing. Or freeze for 1 hr, then give a good whisk and return to the freezer for another hour. Repeat 3 or 4 times until it becomes solid.
