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.
I have been using this recipe for years as an ex-kindergarten teacher. One thing I did discover is that you can microwave any scraps until they are liquid again and then just pour them into the pan and refrigerate them again and make more out of the scraps. That way the kids can use it all to make shapes with cookie cutters.
I have made Jigglers for many years, my daughter is in her 40s now. The one thing I do differently is I line the pan with Saran plastic wrap, leaving some hanging over the edges. This makes it easy to remove from the pan without having to heat the bottom of the pan. Then I use my cookie cutters. I recently sent for the newest Jiggler mold from Jello.com. It is a mold for Jello eggs. You can use an egg slicer to cut them in slices for Jello "coins" to put into dishes of whipped cream!
These were good but I do agree with the others that the extra packet of knox does take away from the taste. We still enjoyed them.
