Here is a foundational authentic ice cream recipe, of which you could add all delights and flavours. Great for a night in. Great for a BBQ. Great for a picnic in the summer. This has no limits.
Flavour variations: ginger -100g chopped stemmed ginger with 4 tablespoons of syrup from the jar. Coffee and brandy - add 2 to 3 tablespoons coffee extract with 2 tablespoons brandy (not for children). Raspberry or strawberry - add 150ml of sieved raspberry puree or 150ml strawberry puree. Rum and raisin - soak 100g of raisins in 4 tablespoons rum for 2 hours. Then stir into ice cream (not for children). Either stick with vanilla or venture and experiment. Incorporating melted dark chocolate/chocolate chips/ mint/ orange/ lemon extract or flavouring/ nuts. You name it. Try making a raspberry puree with 200g of raspberries mashed with 100g of icing sugar, to drizzle over any combination. Any flavour additions should be added to the double cream mixture in bowl 2, then combined with the contents in bowl 1.
