The phrase describes a specific method for creating a fruit preserve. It refers to using the fruit of the Sambucus plant combined with a commercially available pectin product to achieve a desired gelled consistency. The formulation instructions detail the ratios of ingredients, preparation steps, and processing techniques necessary for successful home food preservation. An example would involve gathering the ripe berries, extracting their juice, combining it with sugar and a specified amount of a particular brand of pectin, boiling the mixture, and then pouring it into sterilized jars for sealing.
Employing this specific approach offers several advantages. The pectin product ensures a reliable and predictable set, which is especially important with fruits that may be naturally low in pectin. Furthermore, the resulting spread provides a flavorful way to enjoy the nutritional benefits of the fruit, including its potential antioxidant properties. Historically, fruit preserves have served as a means of extending the shelf life of seasonal produce, allowing for consumption throughout the year.
