Chili and chocolate are a well-documented match made in heaven, and if you're partial to chocolate you can definitely give it a go (as with this recipe for chocolate chili ice cream with a side of cobbler from Macheesmo). There's no reason to stop there, though, and the heat of chili goes with a variety of ice cream flavors you might not have even considered.
If you happen to have an ice cream maker — which is an amazing investment and more affordable than you might expect — there's no end to the experiments that can happen. The Kitchn has this recipe for mango chili ice cream, inspired by the sweet and savory combination that's found in many dishes of southeast Asia. For those who are looking for something light with just a kick of heat, there's also this chili, lime, and lemongrass ice cream from Good to Know, which might just be the perfect dessert for the end of a warm summer's evening. Purists can check out this recipe for chili ice cream, which uses pure chili powder with just a dash of vanilla, some honey, and white chocolate.
If you don't want to make the ice cream itself, don't fret. The Spruce has a recipe for Thai sweet chili and caramel topping that's easy to make, calls for only a handful of ingredients, and is amazing over vanilla ice cream.
