Fine beans, also known in varieties like Elda and Peronas, are appreciated for their smooth and tender pods, which are stringless. They are primarily cultivated in Spain and are available year-round due to greenhouse farming, although their peak season is in spring and summer. These are a healthy food, composed of 90% water, providing vitamins A, C, and B group, as well as minerals like potassium, calcium, and iron. These beans are beneficial for the immune system, help reduce cholesterol, and are diuretic. They are ideal for diets due to their low caloric and fat content. When buying fine beans, look for those with a deep green color and crisp texture. They should be stored in the fridge in perforated plastic bags to maintain freshness. Their versatility in the kitchen allows them to be used boiled, grilled, or as a side dish, particularly complementing serrano ham or extra virgin olive oil.
