Boerenkool, or kale, is a leafy green vegetable popular in the Netherlands. It is known for its curly leaves and is often used in traditional Dutch dishes. Boerenkool is rich in vitamins A, C, and K, making it a nutritious addition to meals. One of the most famous dishes featuring boerenkool is stamppot, which combines mashed potatoes with the cooked greens. This hearty meal is typically served with rookworst, a type of Dutch smoked sausage. Boerenkool is usually harvested in the colder months, as frost enhances its flavor.
