A basic Jell-O jigglers recipe, available on the Kraft website, calls for stirring 2 1/2 cups of boiling water with two eight-serving size packages of any flavor of Jell-O gelatin until combined, refrigerating the mix in a 13-by-9-inch pan until completely firm, and then cutting the firmed Jell-O into decorative shapes. Alternatively, Comfy in the Kitchen offers a recipe for finger Jell-O, that claims to contain the secret to making Jell-O jigglers firm enough to cut and eat by hand.
Kraft’s recipe for Jell-O jigglers suggests refrigerating the mix until the Jell-O firms completely, about three hours, so that the pieces hold their shape and do not crumble. After removing from the refrigerator, hold the bottom of the pan in warm water for 15 seconds, then cut the Jell-O into shapes using 2-inch cookie cutters. After, carefully lift the Jell-O jigglers from the pan with a spatula.
To make Comfy in the Kitchen’s finger Jell-O recipe, combine 3 small boxes of any flavor of Jell-O gelatin, four envelopes of Knox gelatin and 4 cups of boiling water. Stir the ingredients together to dissolve the gelatin, then pour the mixture into a 13-by-9-inch pan, and refrigerate it until it’s firm. Before cutting the Jell-O into pieces or shapes, dip the pan into warm water, and then cut the Jell-O and carefully remove the pieces from the pan.
