March 24, 2026
Formula
10 lbs. Sugar 1 lb. Whisto Jel 1.5 gal. Water 10 lbs. Corn Syrup
Process
Place sugar and Whisto Jel mixed dry into kettle. Add water and bring to a boil.
Stirring constantly, add corn syrup and cook to 224°F.
Cut steam. Add color and flavor.
Place in hot depositor and cast in tempered starch 110°–115°F.
As soon as jellies are cool, remove from starch. Steam and sand in sugar crystals.
Note
Cast fruit jellies can be made by incorporating 4–5 lbs of water packed fruit to the batch after adding the corn syrup.
This process gives a consistent set and works across different flavors depending on the color and flavor added at the end.
Why Whisto Jel Is Used for This Process
Whisto Jel is a standardized pectin powder developed for cast, slabbed, and crystallized jellies, as well as marmalades and jackets. It’s made from natural gelling agents derived from citrus fruits and works as an emulsifying agent in jelly formulations.
One of the main advantages is speed. Jellies made with Whisto Jel set without needing a hot room. Once the product cools, it’s ready to move on to the next step.
That means you can:
remove from starch right after cooling sand in sugar without waiting steam or crystallize right away
There’s no extra holding time just to get the structure to set.
It also keeps the process steady from batch to batch. The set, texture, and handling stay consistent, which matters when you’re running larger volumes or repeating the same product regularly.
