What is To stir or blend ingredients together?

The term you're looking for is "mix".

To mix ingredients means to combine them together in a way that they become evenly distributed. This can be done by:

* Stirring: Using a spoon, whisk, or other utensil to move ingredients around in a circular motion.

* Blending: Using a blender to break down ingredients into a smooth consistency.

* Folding: Gently incorporating ingredients into a mixture without deflating it, like folding egg whites into a cake batter.

* Whisking: Rapidly moving a whisk through a mixture to incorporate air and create a smooth, frothy texture.

There are many other ways to mix ingredients, but the core idea is to combine them until they are well-distributed.
