We recommend: Spice Hunter Arrowroot ($6)
Flavor Notes: This popular thickener has a neutral flavor, but it will give your sauce a shiny, glossy sheen. Be careful not to mix it with dairy, or it will make your sauce slimy.
How to use: You'll need one-half to one tablespoon per cup of liquid. Whisk arrowroot in a tablespoon of cold water to create a slurry. Then whisk slurry into hot liquid. Stir for about one minute until it thickens.
