Tangy cultured milk products, such as yogurt and kefir, pair well with berries of all kinds. Raspberries work exceptionally well with chocolate too. This berry- and kefir-rich ice cream is the best of both worlds.
Combine raspberries, kefir, cream or milk, sweetener, and vanilla extract in a food processor. Process until smooth.
Transfer mixture to ice cream maker and churn according to instructions. Add chocolate chips when manufacturer’s instructions recommend. Finish churning and serve immediately as soft-serve ice cream or freeze to harden.
