Mini double boiler holds 1 quart. Thick aluminum encapsulated base allows for quick, even heating. The 1 quart capacity stainless steel double boiler is ideal for making delicate sauces, tempering chocolate, and making polenta (which can scorch if you're not careful). The curved sides of the double boiler insert make scraping down the sides of the pan super easy so you can efficiently blend and stir the contents. The upper insert and bottom pan are constructed of 18/8 stainless steel. The tempered glass lid with riveted loop handle is oven safe to 450F. The bottom pan may also be used as a one quart sauce pan. This is the perfect size for heating single or double servings of oatmeal or for heating a smaller amount of soup.
