Frequently Asked Questions
What is the fruit-to-sugar ratio for jam?
Traditional jam uses a 1:1 ratio of fruit to sugar by volume. Low-sugar recipes use a 2:1 ratio (fruit to sugar) with special low-sugar pectin. No-pectin recipes typically use a 4:3 ratio.
Do I need to add pectin to all jams?
Not all fruits need added pectin. Apples, citrus, and cranberries are high in natural pectin. Low-pectin fruits like strawberries and peaches need added pectin for a proper set, or a longer cooking time.
