Yesterday I bougth some Jell-O at the grocery store. Yes, I am a 31 year-old man who willingly chooses to buy, make, and eat Jell-O.
Anyway, I looked at the instructions on the packages to make sure I used the right proportions of hot water and cold water. The instructions end with the following admonishment:
Do not add fresh pineapple or kiwi fruit. Jelly will not set.
Who knew that pineapple and kiwi wielded so much power in the gelatin world? Oranges don't have near this level of influence...
