No I just made straight up strawberry jam.Did you use fresh Kiwi and fresh pineapple? They have an enzyme in them that dissolves protein, that might be part of the problem. If you cook them first by themselves, and denature the enzyme, and then add it maybe it will work better. Again, this is a guess. I don't know for sure, but it might give you a research point to go from.
Hey, apparently I was wrong about Kiwi, these people say it is high in pectin.

...and I just confused you as much as me. sorry. Pretend you never read any of this.
Strawberries, lemon juice and sugar. It's all the recipe called for. Boiled it to 220*F. One recipe (conserve) called for 2 pounds of strawberry, juice of one lemon and lime and 4 1/2 cups of sugar.
Most recipes call for canned pineapple.
