A wonderful combination of dark mint chocolate, crumbly biscuit and crunchy pistachios takes this hedgehog-style cake to the next level. And fresh mint ice cream is the perfect addition. Thanks to Yotam Ottolenghi for the cake recipe and to Deborah for making it! The ice cream recipe is from Jeni’s Splendid Ice Creams at Home by Jeni Britton Bauer.

For the cake soak 100g (3½ oz) of sultanas in 2 tablespoons of rum for 30 minutes. Line a 28cm x 18cm (11″ x 7″) baking tray or glass dish with greaseproof paper. Set a large heat-proof bowl over a saucepan of gently simmering water and add 100g (3½ oz) of mint-flavoured dark chocolate, 200g (7 oz) of dark 70% cocoa solids chocolate (both roughly chopped into 3cm pieces), 100g (3½ oz) of golden syrup, 120g (4¼ oz) of unsalted butter cut into 2cm (¾”) cubes and ⅛ of a teaspoon of salt. Make sure the bowl isn’t touching the water or the mix will get too hot and split. Heat and stir for two to three minutes until melted and combined. Add the sultanas and their soaking liquid, 170g (6 oz) of roughly broken digestive biscuits and 75g (2½ oz) of roughly chopped pistachios and mix until everything is well coated. Transfer it into the lined tray and smooth the top. Sprinkle with an extra 25g (¾ oz) of crushed pistachios and set aside to cool for 10 minutes. Cover the tray and refrigerate for two to three hours. When set, cut into strips and store in an air-tight container in the fridge. Serve cold. For the mint ice cream measure 2 cups of milk. Take out 2 tablespoons of the milk and make a slurry with 6 teaspoons of cornflour (cornstarch). Heat the remainder of the milk in a saucepan with 1¼ cups of heavy cream, ⅔ of a cup of sugar and 2 tablespoons of glucose (in Australia I use this in place of light corn syrup). Bring to the boil and allow it to simmer for 4 minutes. Remove from the heat and pour in the cornflour slurry. Stir, return to the heat and allow to thicken. In another bowl whisk 3 tablespoons of softened cream cheese with ⅛ of a teaspoon of salt. Pour in the hot milk mixture and whisk until smooth. Now tear a bunch of fresh mint leaves into the hot mixture and cool the mixture down in an ice bath. When the mixture is cold strain out the mint leaves and freeze with an ice cream machine, sorbetiere or even over ice and salt. If you have flexible silicone moulds, transfer the nearly set ice cream into them for ready-to-serve portions.
