I thought this glass block Jell-O looked so cute when I saw it on Our Best Bites. I just had to make it. What's funny, though, is I don't really love Jell-O unless it's been spruced up, like this or this. So, even though the recipe made a festive side dish for St. Patrick's Day, I didn't think the taste was anything special. You Jell-O fanatics out there will probably beg to differ.
4 3-ounce packages Jell-O, any colors
2 packets unflavored gelatin (such as Knox)
1 14-ounce can sweetened condensed milk
Find as many containers as you have colors of Jell-O -- Tupperware or glass baking dishes will do. I used an 8x8 baking dish for my green because I had three packages of it. I used a small square plastic container for my yellow because I only had one package. If you choose four different colors, you will need four small containers. Spray with cooking spray. Clear out a shelf in your fridge.
Mix 1 cup boiling water with each package of Jell-O. That's it. Stir until dissolved and pour into containers so that Jell-O is up to an inch deep. Refrigerate several hours, or until firm.
Mix unflavored gelatin with 1/2 cup cold water. Let stand until thickened. Add 1 1/2 cups boiling water and sweetened condensed milk. Allow to cool while slicing colored Jell-O into small squares and tossing together in sprayed 9x13 pan. Pour milk mixture over all. Try to poke down any squares that want to stick out. Refrigerate overnight.
