It's not actually glass....it's jello but when you add all the colors together with the filling it looks like it could be!
Make a graham Cracker crust and put it in a springform pan reserving about 2 T. to sprinkle on top.
1pkg each of (Small Jello packets)
(we also use Orange Jello and you can get any color you would like to add also)
Dissolve each of these in separate trays with 1.5 cups of boiling water.
Put in the fridge to Set firm.
Mix 1 T. plain Gelatin with 1/2 C. cold water.
Whip 1 Pt. whipping cream with 2 T. sugar (I use Powdered sugar to avoid graininess)
add 1/4 C. hot canned pineapple juice and 1/4 c. hot water and 1 T. sugar to the plain gelatin mixture. Mix and add to whipped cream.
Cut Jello into small cubes and shapes.
Add Jello to the whipped mixture.
Put into the crust in the springform pan.
Sprinkle reserved graham cracker topping and refrigerate till ready to serve.
NOTE: we tried this with Cool Whip recently and it worked! So those non-dairy types have something new and fun to enjoy!
