Grandma Dot's Easter Jello

This post is for all of my sisters! I remember calling Grandma for this recipe and was so happy to find it today. It would be fun if we all made it in honor of Grandma. I can still see it on her table. I love that Grandma mastered the art of cooking and baking. She took pride in all areas of homemaking! She told me over and over again how when she came to the states she didn't know how to boil water! Happy Easter!
