All products in the Dietella line are: durable, hygienic, and safe because the enamel covering the entire surface of the utensil is impervious to acidic substances like lemon juice, vinegar, tomatoes, and does not absorb moisture or odors. It allows boiling, grilling, frying, slow simmering, stewing, and oven-gratinating, while significantly saving energy as once the desired temperature is reached, only a small amount of heat is needed to maintain it for a long time.
