We recommend: Bob's Red Mill Guar Gum ($10)
Flavor Notes: Guar gum is a neutral-tasting thickener frequently found in a wide range of products like dressings, ice cream, and even toothpaste to act as a binder and thickener. It is much stronger than cornstarch, so use it sparingly.
How to use: Use between one-fourth to one-half teaspoon per cup of liquid. Whisk the guar gum in a tablespoon of cold water to create a slurry. Then whisk slurry into hot liquid. Stir until completely dissolved.
