1 (14-ounce) can sweetened condensed milk (don’t get evaporated milk)
2 envelopes unflavored gelatin (that Knox stuff)
4 small boxes (3-ounce) of Jell-O or store brand “gelatin dessert” in different colors
For each flavor, dissolve one box of jello in one cup of boiling water. Pour into a container and chill (overnight is probably best, but I chilled it 3 hours until firm). After chilling the four flavors, cut them into small blocks.
Carefully mix the blocks in a 9 x 13 pan.
In a separate bowl, sprinkle 2 envelopes unflavored gelatin into 1/2 cup cold water. After the gelatin blooms, add 1 1/2 cup boiling water and dissolve. Add the can of condensed milk. Stir and cool. Pour cooled milk mixture over jello and chill overnight.
Cut into blocks or shapes and serve!
