When would you use a slurry, and which starches are commonly used?

• A. To thicken a sauce near the end of cooking; cornstarch or arrowroot mixed with cold liquid.
• B. To emulsify sauces during initial cooking; flour or cornstarch mixed with hot liquid.
• C. To glaze meats; potato starch used hot.
• D. To clarify consommé; gelatin and starch used.

Answer: (D)

Slurries are used to finish-thicken a sauce or soup by whisking a starch with cold liquid and then stirring it into hot liquid. This method helps prevent lumps and lets you control the texture toward the end of cooking, reducing the risk of over-thickening or breaking an emulsion if the sauce is kept at high heat. The starches most commonly used are cornstarch and arrowroot. Cornstarch gives a smooth, opaque body and thickens well with heat; arrowroot thickens at a lower temperature and yields a clearer, glossier finish, though it can break down with prolonged simmering or acidic ingredients. Other starches like potato starch or tapioca can be used in slurries, but cornstarch and arrowroot are the standard pair.
