How should I store the jam after opening, and how long can I keep it?

Proper storage helps keep the jam in good condition and preserves its flavour. Before opening, keep the jar in a cool, dry place away from direct sunlight, and follow the best-before date printed on the label. Once opened, the jam should be refrigerated to slow down any changes in texture and aroma. Always use a clean, dry spoon when taking out the jam, and close the lid tightly after each use. This avoids introducing moisture or bacteria that could cause spoilage.

As with any sweet preserve, the sugar content helps to preserve the product, but it does not make it immune to spoilage once the jar is opened. For the best quality, try to consume the jam within a few weeks to a couple of months after opening, though the exact time depends on how it is handled. Always rely on your senses: if you notice an off smell, visible mould, or a change in texture, discard it. If you prefer a longer shelf life, you can also store the unopened jar in a cool pantry, but always check the manufacturer's recommendations on the label.

Remember that this is a sweet product with sugar and citrus peel, so it is not a low-sugar option. If you are following a specific diet, check the ingredient list on the jar for the full nutritional information.
