A strong spearmint-like mint native to Australia, River Mint is a great alternative to regular mint. We love it in sweet dishes, such as this ice-cream; and it also makes a great Aussie cucumber raita to have with lamb.
If you don’t have an ice-cream maker, pour the ice-cream mixture into a shallow container and freeze until almost solid. Whisk with an electric hand whisk, then refreeze. Repeat 1-2 times, then freeze until solid.
