Spinach is a leafy green vegetable that can be eaten raw or cooked. It is high in vitamins A and C, as well as folate and potassium. To clean spinach, rinse it with cold water and then drain it. Remove any large leaves or tough stems with a vegetable peeler or a knife. Cut the spinach into small pieces and place it in a bowl. Add enough cold water to cover the spinach and stir to mix. Let the spinach soak for 10 minutes, then drain it again. Spinach can be stored in a covered container in the refrigerator for up to four days. ..
