The Knox Blox I Remember - cooking recipe

Ingredients

3 (1/4 ounce) envelopes unflavored gelatin (Knox)
4 (3 ounce) boxes Jello gelatin (any flavor)
4 cups boiling water

Preparation

Put Jello and Knox gelatin into a bowl. Add water and stir until dissolved.
Pour into 9x13 inch pan. Cool in refrigerator.
When firm, (4 to 5 hours) cut into squares. I've used the chill time as the cook time.
