Mixing together different ingredients is a common task in many areas of life. Blending, pooling, and stirring are all terms used to describe the process of combining two or more substances. Blending is the process of combining two or more ingredients into a single mixture. Pooling is the process of combining two or more liquids into a single container. Stirring is the process of mixing two or more ingredients together using a spoon or other utensil. All three of these processes can be used to mix together different ingredients, resulting in a single mixture.
