Stews are a heartier and more substantial meal than a soup, and often require the use of a thickening agent to attain their traditional, savory base. When preparing stew, you can control the texture and viscosity of the liquid by using a mixture of flour and water or stock. Use equal parts of both ingredients to form a slurry that you can add slowly during the cooking process until the desired thickness is achieved.
Measure ¼ cup of flour and ¼ cup of water or stock and pour into a container with a lid. Place the lid onto the container and shake for 30 seconds to mix.
Measure 1 tbsp. of the flour and liquid mixture and add it to the stew.
Stir the stew with a wooden spoon until the slurry is well incorporated. Ensure the stew is simmering, but it does not have to be at a rolling boil.
Wait two to three minutes to observe the thickness of the stew. If the stew still needs a thicker consistency, repeat the process until the stew is as thick as you would like.
