As a recipe tester, your duties are to test recipes before food goes into production or before the release of a cookbook or recipe article. You may also help other food scientists, chefs, and writers develop and create new recipes for commercial purposes. Your principal responsibilities are to collect ingredients, measure them according to the instructions in the recipe, and cook them according to the recipe. You make careful notes, time how long the preparation and cooking take, and provide feedback to chefs or other culinary specialists.
