Welcome to our guide to jam making equipment, primarily the jam funnel. A jam funnel is an important piece of preserving equipment and should be part of any good preserver's arsenal of tools. Jam funnels differ from a normal funnel; they have a wider mouth at the bottom which allows them to be rested in an empty jar while homemade preserves are poured in. The major advantage of using a jam funnel when filling jars is the avoidance of contact between the preserve and the rim of the jar; a clean seal is required to ensure the contents do not spoil.
Jam funnels are manufactured from various materials and their performance ultimately depends on the materials, their quality and the design of the funnel. Some feature handles to help steady the funnel whilst in use. Overall, a jam funnel is considered to be a fundamental part of a smooth and successful jam making experience.
