jam.

Once opened, jam typically lasts for 6 to 12 months in the refrigerator if handled with clean utensils.

Jam is made from crushed or chopped fruit, while jelly is made only from the fruit juice, resulting in a clearer, firmer consistency.

Yes, jam can be frozen for up to a year, though the texture may become slightly more watery upon thawing.

Look for signs of mold on the surface, an off-smell (fermented or sour), or significant changes in color and texture.

Fruit preserves, fruit butter, honey, or a thick fruit compote are the best alternatives.

Most commercial jams are vegan as they use pectin (a plant-based fiber) as a thickener, but always check labels for honey or gelatin.

Sugar crystals can form if the jam is stored for a long time or if the sugar-to-fruit ratio was slightly off during cooking; it is still safe to eat.

Look for brands where fruit is listed as the first ingredient and that contain minimal additives or high-fructose corn syrup.
