Used for the preparation of jellies and sauces, this utensil is a common tool when canning various types of foods. There are several variations of design for the Jelly Strainer, but most all include a fine meshed, nylon filter bag that strains out excess materials so the result is a very clear mixture, such as is desired for jelly or a clear sauce. The Jelly Strainer will often include a metal structure that holds the filter bag tightly secured to the rim and positioned so the mixture being strained falls through to a collecting pan below.
