An egg-whisking utensil is a BEATER, which is a six-letter word. A BEATER is a kitchen tool used to mix ingredients together quickly and efficiently. It is usually made of metal or plastic and has a handle with a flat or curved blade at the end. The blade is used to beat or whisk eggs, cream, and other ingredients together. Beaters are also used to make batters for cakes, cookies, and other baked goods.
