Yes, you can! I pit the plums and chop them in big pieces, then freeze in a food storage bag. To make jam from frozen plums, simply add them to the Instant pot without thawing, and continue the process. Since frozen fruit released more liquid, you will have to simmer the jam for a bit longer after pressure cooking.
Can you use frozen fruit for jam making?
“Frozen fruit can be used very successfully,” says Pam Corbin, author of Pam the Jam: The Book of Preserves, who recommends buying from britishfrozenfruits.co.uk. “However, if the fruit is wet, or over-ripe, and then frozen, this may result in runny jam.”
Do I defrost fruit before making jam?
Get them into the jam pot before they thaw; the faster they defrost, the less juice escapes the fruits. This makes a thicker, tastier jam.
Can I use frozen fruit instead of fresh fruit?
In many cases, frozen fruit is picked at its peak ripeness and then flash-frozen to preserve its flavor and nutrients. That means that frozen fruit is often just as good as fresh fruit, but it’s more convenient because you can store it in your freezer for months.
Does freezing fruit destroy pectin?
There are two types of pectin, liquid (usually made from apples) and dry (from citrus fruits or apples). Powdered pectin can be stored in the freezer from one season to the next. Freezing will destroy the gel-producing qualities of liquid pectin, but liquid pectin will keep for two years in a cool, dry place.
Does frozen fruit need to be defrosted?
Frozen fruits and berries are safe to consume raw, cooked or even frozen out of the bag. However, frozen vegetables should always be cooked before consumption to minimize any foodborne illness risk.
Do you peel plums for jam?
Plums and nectarines should be peeled, as their skins can be tough / chewy in jam. If you do want to leave the skins in, you might want to run the fruit through a blender or food processor to chop them up (after you remove the pits, of course).
Should you stir jam while it’s boiling?
Do no stir jam once boiling, but use a wooden spoon to check it is not sticking on the base of the pan. Stirring lowers the temperature and delays setting point being reached. It is wasteful to remove scum too often. Do it at the beginning and at the end.
Why is my homemade jam runny?
The natural pectin in fruits and vegetables thickens jams. If there isn’t enough pectin in the fruit itself and you don’t add extra pectin, the result is runny jelly or jam. Additionally, if the fruit is overripe, its pectin levels are lower.
What is the ratio of sugar to fruit when making jam?
1:1
The amount of sugar you need to make jam depends on the amount of pectin in your chosen fruit, but generally the fruit-to-sugar ratio for traditional jams is 1:1 (ie. 450g/1lb sugar to 450g/1lb fruit).
Does freezing fruit increase sugar content?
Vegetables are often blanched prior to freezing to prevent browning, this process also retains phyto-nutrients, including carotenoids and flavonoids. Salt and sugar levels may be a little higher in frozen fruit and vegetables. For example, frozen peas have 5.9g sugar per 100g compared to 1.2g in fresh peas per 100g.
Why is frozen fruit better than fresh?
Because most frozen fruits and veggies are frozen shortly after they’re harvested, they’re allowed to ripen fully, which means they’re chock full of vitamins, minerals, and antioxidants, and freezing “locks in” many of their nutrients, according to the Academy of Nutrition and Dietetics.
Does freezing fruit destroy nutrients?
Generally speaking, freezing helps retain the nutrient content of fruits and vegetables. However, some nutrients begin to break down when frozen produce is stored for more than a year ( 2 ). Certain nutrients are also lost during the blanching process. In fact, the greatest loss of nutrients occurs at this time.
How can I thicken jam without pectin?
If you simply take fruit and cook it with some sugar to sweeten it a little, it will get thick enough to turn into jam by the naturally occurring pectin in the fruit and the process of reduction. Reduction occurs when we simmer the fruit, and the liquid turns to steam and evaporates, which thickens the jam.
How do you fix runny jam without pectin?
Without Adding Pectin
- Pour the soft jam or jelly into a medium-sized pot and add 2 tablespoons of lemon juice for each quart of jelly you measured.
- Bring it to a boil over medium-high heat for 3 to 4 minutes.

Frozen fruit in the package can be thawed in the refrigerator, under running water, or in a microwave oven if thawed immediately before use. Turn the package several times for more even thawing. Allow 6 to 8 hours in the refrigerator for thawing a 1 pound package of fruit packed in syrup.
How do you keep frozen fruit from getting soggy?
Prevent a mushy mess by freezing berries on a baking sheet in a single layer first. The exposure to the cold freezes them quickly. This prevents the formation of large ice crystals, which destroys cell walls and makes berries lose their structure and become soft when they thaw.
