Vanilla-Maple Yoghurt And Cream Ice Cream

We have a heatwave. What better time to make some ice cream! Well, so long as the kitchen isn't too hot. I've attempted to make ice cream in the past when the kitchen was sweltering, and it didn't go so good. Fortunately my kitchen was not sweltering, well, not when I made the ice cream, at least.

( Igor, fetch the maple sugar. Not the maple syrup, you imbecile, the maple SUGAR! )
