Always Preheat Your Slow Cooker Before Adding Ingredients
By S. Ferrari
Rather than tossing all of your ingredients into a cool cooker to warm up together slowly, take a few minutes to preheat the apparatus while you prepare the ingredients.
However, placing these ingredients in a cold slow cooker will cool them down. If you preheat your slow cooker beforehand, your ingredients will maintain an optimal temperature.
This step will also prevent some food-borne illnesses by minimizing the amount of time your food lingers in the temperature danger zone between 40 and 140 degrees F.
