The most important tool in the kitchen is the measuring cups. because when we were doing our muffin recipes it came in handy a lot. and not just for the muffin recipe for others as well like the cookies recipe. the reason why I think this the best tool is when ever we deal with liquid ingredients or flour or baking soda or salt it makes sure you put in the right amount in. to make sure you do the recipe right witch is why this is the best tool in the kitchen
