Mis en Place is a cooking technique that really helps things to go smoothly in the kitchen. Especially when you are preparing recipes where the different steps go rather quickly. It basically means to prep everything ahead of time so all you need to do when it is time for the next ingredient or step is to turn and grab it. Try it out – it really makes cooking much more enjoyable and relaxed !
It is defined at wikipedia as:
Recipes are reviewed, to check for necessary ingredients and equipment. Ingredients are measured out, washed, chopped and placed in individual bowls. Equipment such as spatulas and blenders are prepared for use, while ovens are preheated. Preparing the mise en place ahead of time allows the chef to cook without having to stop and assemble items, which is desirable in recipes with time constraints.
