Homemade strawberry preserves don’t last long in their original form, but with proper storage, they can last quite a while. We usually keep them in a properly sealed jar, stored in a cool, dark place, for up to a year. Once opened, we move them to the refrigerator. We prefer to use the preserves within a week or two after opening to ensure they stay fresh and don’t spoil.

1: Recipe
1,000g (2¼ pounds) of strawberries: Use fresh, ripe berries. 350g (1¾ cups) of sugar: This helps create sweetness, thicken the jam, and preserve it for a longer time. 1 packet of Gel Fix Super: Some people prefer to skip this ingredient and use the traditional method of cooking the fruit with sugar instead. While this may take longer, it results in a classic soft-set jam.
2: Tools
- Cutting board and knife
- Large pot
- Wooden spoon or heatproof spatula
- Measuring spoons
- Clean glass jars
- Canning funnel
- Towel
3: Instructions
1. Cut the strawberries into small pieces and place them in a large pot.
2. In a separate bowl, mix the contents of the Gel Fix Super packet with 2 tablespoons of sugar, and then add this mixture to the pot of strawberries.
3. Boil the strawberries for 1 minute while stirring constantly.
4. Add the remaining sugar to the pot and boil for about 5 minutes.
5. Skim off any foam that forms on the surface, then fill your jam jars while the jam is still hot.
6. Clean the edges of the jars, seal them with lids, and turn them upside down.
4: Strawberry Storage Tips
1. **Room Temperature Storage**
Store the jar in a cool, dark place, like a cupboard, away from heat and direct sunlight. When stored properly, it can last for up to a year.
2. **Refrigerate After Opening**
Once you open the jar, refrigerate it and keep the lid tightly closed to maintain freshness. Always use clean, dry spoons. Avoid double dipping or using utensils that have come into contact with other foods, as this can introduce bacteria and lead to spoilage.
3. **How to Freeze Jam Without Canning**
You can freeze jam instead of canning it. Start by cooling the jam, then pour it into freezer-safe containers, leaving some space at the top to allow for expansion. It can be stored in the freezer for up to a year. According to the University of North Dakota, fruit-based products should be frozen at 0°F for 8 to 12 months. Once the jam has been thawed or opened, consume it within 2 to 4 days. When freezing jam, use wide-mouthed, airtight jars and avoid jars with shoulders, as they may burst under pressure.
4. **Use opened preserves within a month**
For the best taste and safety, consume opened preserves within a month.
5.** Always shake the jar before using it**
Keep an eye on the jar, even when it’s closed, and check for any unusual odors. If the contents appear off in any way, don’t take any chances—just toss it.
When in doubt, throw it out.
Be on the lookout for these five signs; if you notice any of them, it’s time to discard that jar of homemade strawberry jam because it has spoiled.
- – Mold growth
- – Unusual odor
- – Changes in color
- – Altered texture
- – Condition of the lid
