Product review (5 stars): Just what I needed.
I have a Kitchen Aid Artisan mixer with a glass bowl. I also have the ice cream attachment. This cover is perfect for cooling the creme anglaise overnight before pouring it into the ice cream maker. I like it better than putting tin foil over the bowl.

It's a nice snug fit and not expensive. (I think it should be standard when ordering the mixer, it's that useful).
