In the kitchen and how to use it

Smooth peanut butter without salt is made by grinding roasted peanuts into a spreadable paste, used most often on bread and crackers, stirred into oatmeal or smoothies, or as a dip for apple slices and celery. Its dense, creamy texture and rich, roasted peanut flavor also make it a common ingredient in baked goods like peanut butter cookies, and in savory dishes like satay sauce or noodle bowls. Because it is unsalted, its flavor leans more purely toward roasted peanut without the added savoriness a salted version would bring.

Store peanut butter in a cool pantry, and refrigerate it once opened if it does not contain stabilizers, stirring natural-style versions before use since the oil can separate. A tablespoon (32 g) serving comes from a food that is calorie-dense at 598 calories per 100 g, so it is measured by the spoonful rather than spread thickly. Per 100 g it provides 61% DV vitamin E, 44% DV protein at 22.2 g, 40% DV magnesium, and 5 g fiber, and with only 17 mg sodium per 100 g thanks to being unsalted, it leaves room to season a dish separately, making it a useful protein and vitamin E contributor to breakfasts, snacks, and sauces.
