What must you do before par cooking?

Before par cooking, it’s essential to prepare your ingredients by cleaning, peeling, and cutting them into uniform sizes for even cooking. Additionally, ensure you have all necessary equipment and tools ready, such as pots, pans, and utensils. Preheating your cooking medium, whether it's water for blanching or oil for frying, is also important to achieve the desired results. Finally, plan your timing to ensure that all ingredients are par-cooked appropriately.
