Notes
You won't want to share. I put that this makes enough for 12 but it really makes more than that and I don't know how to figure that. It's basically a stick of butter, so plan accordingly.You can serve this with waffles, bagels, toast, rolls, pancakes, and banana bread - and anywhere where sweet butter makes sense.
