I get really frustrated with Jello that doesn't set-up. I have made these "fool-proof" jigglers a million times for my kids. It's the only recipe I've used that's firm enough to cut out with cutters. Very easy for kids to make, too.
- *This recipe does not contain any cold water Combine Knox gelatin and Jello with boiling water and whisk until completely dissolved (about 2 minutes).
- Pour into a lightly greased 9x13 pan and let set in refrigerator until firm.
- Cut into squares or use cookie cutters.
