You should definitely try them! They are lots of fun.

The bowls came from Crate and Barrel (called Addison bowls, I believe; I have mixing bowls that match), but it looks like they’ve been discontinued. They’re about the size of ramekins, though maybe a bit taller. I use them all the time as little prep bowls, and I thought they’d work better here than ramekins since they have a rounded bottom.

What are the little cups that you used as molds? Ramekins? They look smaller than that but hard to tell.

By the way - your pictures are really great!
