I can't believe that this isn't already up- This is my family's recipe, and it is soooo easy and fabulous- you never need to mess with cooling or jelling, and it can be made a little more dietetic if you use low-fat or non-fat milk and cream cheese:
2 pkg jello (any flavor)
1 can crushed pineapple in own juice- do not drain.
8 oz cream cheese
i can evaporated milk
pecans or walnuts( optional)
sliced marschino cherries (optional)
Put entire can of pineapple in saucepan and bring to a boil. Add jello, cook until dissolved, stirring constantly. Mix in cream cheese (a hand mixer helps here) until smooth, stir in evaporated milk and nuts and/or cherries if using them. Pour into mold.
My husband likes this so much I occasionally make it between holidays as a dessert!
