“My Italian Water Ice I made yesterday is hard as a rock. It’s impossible to scoop.”
Over the years, I keep hearing the same question. Fear no more, here’s the answer — a cold water activated stabilizer. So, what the heck is a stabilizer? Do I really need to use one? How are they used? Italian water ice and sorbets have long been enjoyed as seasonal fun-foods. Because they yield a greater cooling effect than ice cream, they are ideal warm weather treats. For a water ice to be enjoyed by the consumer, the product usually will need help. That help comes from the use of a stabilizer.
Stabilizers provide creamy meltdown and smooth texture while also preventing the ice crystallization and coarseness associated with heat shock (common language – why are they so hard to scoop). They make scooping easier, and they extend shelf life. Most stabilizers for water ice or sorbet production are made up of:
- Guar Gum: Retards ice crystal growth nonspecifically by slowing mass transfer across the solid/liquid interface. It shows good stability during freeze-thaw cycles.
- Exanthan Gum: Helps create the pleasant creamy texture in ices.
All the recipes in our books and newsletter use the stabilizer 9100 from Main Street Ingredients – a cold water stabilizer that is simple to use. It’s used at the rate of .20-.30% by weight. If your finished product seems too soft or stringy, you used too much, so be careful, less is better than more.
Usage level is 8 grams for a 2½-gallon batch and 12-16 grams for a 5- gallon batch. Simply mix the stabilizer with dry sugar and add to liquid ingredient(s) with good agitation. Allow a few minutes for the stabilizer to hydrate before freezing.
