It does need to be a decent jam though, and I favour the Bonne Maman conserves.I've also had luck with blackcurrant with cassis and apricot with amaretto but I always, always go back to the favourite; strawberry with triple sec. There's something about the orangey alcohol that just seems to bring out the true flavour of the strawberries and this has been described to me by more than one person as the most strawberry-ish strawberry ice-cream they've ever had. Not bad for five minutes' work!
284ml carton whipping cream
370g jar of jam (and see above)
2 tbsp booze of your choosing (and see above)
juice of half a lemon.
Stiffly whip the cream. Stir the jam, alcohol and lemon juice together, then fold this mixture into the cream until thoroughly combined. Pour into an airtight plastic container and freeze. Transfer the box from the freezer to the 'fridge about twenty minutes to half an hour before you want to serve the ice-cream. I normally do this as we sit down to eat, which is easy enough to remember. Dish it out with an ice-cream scoop dipped in hot water for ease.
