Make sure to leave any holes near the container’s lid uncovered. Remember, raspberries do require some air circulation to remain fresh.
Instead of placing the raspberries in a cold portion of your fridge, place them where you’re likely to see them. You will eat raspberries quicker if they’re easy to reach, preventing them from going bad.
How long they take to freeze depends on the amount you’re freezing and the strength of your freezer. Check on the raspberries every half hour ago until they’re hard and frozen throughout.
Place the berries in a sealable container, such as a mason jar. Pour in your syrup mixture until there’s about half an inch of headspace on the top of the jar. Seal the jar and place the berries in the freezer.
Moldy raspberries will have white fuzz growing on them.
Instead, use a colander. Set the raspberries in the colander. Fill a bowl with cold water. Dunk the colander into the bowl of cold water. Swish it around slightly to wash the berries.
Submerge your berries in the vinegar and water mixture. Wash the berries gently in the mixture. Use the mixture to remove any visible dirt and grime from the berries. This process should also remove any spores that could cause mold. When you’re finished, dry the berries completely and then store them. Avoid soaking in mixture for too long, as the berries will absorb the vinegar flavor. Just dip in, and dip out.
Dunk the raspberries in the hot water for about 30 seconds. Remove the berries from the water, dry them off, and store them.
