Pamela, I usually make jell-o jigglers within an 8-inch Teflon coated pan, to ensure they are a little bit bit bigger, however when I wish to make these questions 13x9x2-inch pan, I personally use 8 boxes from the jell-o, plus 5 glasses of boiling water. Earlier this weekened I made jell-o jigglers while using 2 new gelatin flavors, Tropical Fusion (a mix of cherry, orange and pineapple) as well as the Blackberry Fusion (a mix of blackberry and raspberry). Everybody enjoyed them. Another factor I needed to say, if one makes your jello jigglers in Teflon coated pans, you don't need to dip bottom of pan in tepid to warm water for just a few seconds to release the gelatin. Pamela, appreciate writing this recipe, so others could make them also.
I must provide a suggestion: line your pan with Saran wrap when jelled, lift from pan and reduce your shapes. Make use of a wet metal spatula to lift the shapes. I've discovered this an simpler method to handle these jigglers. HTH
I additionally make these. Because we drink a lot of pure oj, I save the orange shells and employ these for molds. For everyone towards the kids, I cut the orange halves into wedges for simpler eating. Kids loved these.
