I used the whole #2 can of crushed pineapple mixed with 2 cups of sugar and cooked down until thick.
The recipe also calls for 1 cup port wine, 6 egg yolks (whites beaten and folded in last), 4 cups pecans, 1/2 lb margerine, 16 oz marschino cherries cut in half, 2 more cups of sugar.
Your recipe sounds VERY similar. Where did it come from? Let me know if you want the exact recipe.
