Dessert

Blitz the digestive biscuits and pretzels into crumbs, mix with melted butter and press firmly into the base of an 8-inch/20cm deep springform tin, chill in the fridge to set
Whisk cream cheese with vanilla extract and icing sugar until smooth, then add caramel and whisk until lump-free
Pour in double cream and sea salt, whisk until very thick and mousse-like, spread the mixture over the chilled biscuit base and refrigerate overnight
Remove the cheesecake from the tin, drizzle spare caramel over the top and scatter toffee popcorn and remaining pretzels to decorate
