HIC Roasting's Borosilicate Glass Gravy Separator strains out fat and seasonings from liquids and pan drippings for rich flavor without any lumps. The glass wide-mouth pitcher with ¼-cup markings makes pouring and measuring easy. It's stovetop and microwave safe (to 300-degrees Fahrenheit) for easy reheats. This gravy strainer, or fat separator, has a pierced strainer to sieve out lumps and larger food bits, and a removable fine-mesh screen to filter out finer particles. The low-set spout pours liquids out without any fat. The generous 4-cup (32-ounce) pitcher processes a large volume for everyday meals and holiday entertaining. Quickly strain out fat, herbs, seasonings, lumps, and other food bits.
