I'm sure if you are a Downton Abbey fan, you have seen jello molds.
Jello molds have been used in kitchens long before Mrs. Patmore and Daisy were making meals. They come in both ceramic, glass, and copper and during the 1950's and 60's aluminum was all the rage. My grandmother made many a jello salad.
I don't use them for jello very often, but I love the way they look, especially the ceramic and glass variety. I re-purpose them as dip or sauce containers and use them with my crudites, fruit or cheese platters etc. Here I've used one for my favorite Meyers lemon yogurt sauce!
