Fruit or vegetables: not the same method
Jams, fruits in syrup and compotes are acidic: a boiling water bath is enough. Low-acid vegetables (green beans, peas, ratatouille…) need a longer processing — ideally in a pressure canner — or another method such as lacto-fermentation. The details are in our guide on how to sterilize your jars.
Pumpkin and squash are a special case: never can them as a purée, which is too dense for the heat to reach the centre of the jar. Freeze the purée, or can the flesh in cubes in a pressure canner.
Plan your season
Before the big batches of summer, take stock of what is left in your pantry: there is no point in making ten more jars of a jam you still have plenty of. Jarrito shows your stock by category and the date of each batch, so you know what to make this year — and what to eat first.
