The phrase refers to a set of instructions for producing a fruit preserve using strawberries as the primary ingredient and a specific brand of pectin, Sure-Jell, as the gelling agent. The instructions typically outline the required quantities of strawberries, sugar, pectin, and potentially lemon juice, along with the step-by-step process of combining these elements, cooking the mixture to the appropriate temperature, and then processing the resulting jelly for safe preservation.
Creating homemade strawberry jelly using a reliable pectin product offers several advantages. It allows for control over the ingredients, potentially reducing the amount of sugar compared to commercially produced options. The process connects individuals to traditional food preservation techniques, fostering self-sufficiency and a greater appreciation for seasonal ingredients. Historically, pectin-based jelly making has been a staple of home cooking, providing families with a shelf-stable product for extending the enjoyment of fruit harvests.
