What effect will the enzymes in canned pineapple have on gelatin?
If bromelain (enzyme) comes in contact with the gelatin (protein) in the hot solution, the bromelain will break down the protein into smaller pieces. These smaller pieces won’t be able to trap the water and other smaller molecules into the pockets that give gelatin its form.

Why did my gelatine go lumpy?

How can you tell if gelatin is dissolved?
It takes time as well as temperature to dissolve gelatine. So stir for at least two minutes (or longer if the recipe says so). You’ll know the gelatine is completely dissolved when there are no visible granules remaining.
What is the source of Knox gelatin?
