Before the very first recipe in Mastering the Art of French Cooking Julia Child wrote:Although we are enthusiastic about the electric blender for many things, we almost always prefer a food mill to a blender when a soup must be puréed. There is something un-French and monotonous about the way a blender reduces soup to universal baby pap.
Unfortunately this delightful passage was rewritten in later editions of the book. I followed her original instructions for
Potage Parmentier—the recipe where the above appeared—to the letter, using a Foley food mill. It was delicious, with excellent texture, most certainly not pap. I like food mills but don't currently have one in my kitchen.
