How to make plum jam without pectin
Plums are truly the perfect stone fruit to make jam with, as you don’t need to remove their skin. The skin actually has pectin that helps the jam to thicken and gel.
What exactly is pectin?
Pectin is an important part of jam making. It happens to be a naturally occurring starch that can be found in some fruits. When you cook the plums with the sugar, the pectin is released and naturally thickens the jam. Since plums are naturally pretty high in pectin, there is no need to add any additional pectin.
Ingredients in this recipe:
- Plums –This particular jam was made with the gorgeous ruby-red flesh plums. It makes a stunning and bright colored jam. You could use whichever plum variety you like. by-red flesh.
- Sugar – Granulated sugar is what I typically use. I’ve made it with coconut sugar and do not like the consistency as much as I do when I make with granulated sugar
- Lemon juice – Freshly squeezed is the only lemon juice I recommend. The recipe is not the same without the fresh lemon juice, as it helps the jam to set and also makes it not too sweet.
How to pick the best plums for this recipe
Look out for good quality, freshly picked fruit. The best plums to use are ripe with nice and firm skin. The firm skins have more pectin and you’ll end up with a really nice textured jam. Avoid buying really soft and over-ripe plums (no bruised plums!)…your jam will not last that long.
Do I have to peel the plums to make this jam?
No, peeling the plums is not necessary. Leaving on the skin is the best method. The skin has pectin in it which actually helps set the jam.
Can I use less sugar?
You could try to make the recipe with less sugar, but it will affect the way it sets and also, how long it remains fresh. I suggest to make the jam with the amount of sugar that the recipe calls for. It does seem like a lot, but when it’s cooked up with the fruit, the flavor balances out. If you do make it with less sugar, just store the jam in the fridge until you’re ready to eat it (and after you open it).
Can the jam be made without lemon?
Fresh lemon juice is essential to the recipe. It has a high amount of acid and pectin, which will help the jam to set. The tartness of the lemon also helps to balance out the sweetness.
Let’s make this delicious plum jam together!
- This is a totally pectin-free recipe! Some jam recipes call for 1:1 ration of fruit to sugar or even 1.5 ration to 1. Some recipes even use 2:1 ratio of fruit to sugar.
- Mom’s recipe that we are using is 1 1/2 cups (300 grams) of granulated sugar used with the 2 lbs of fruit. Mom said for plums, that it is the perfect amount of sugar, and that it brings out the fruits’ natural sweetness (I can’t ever argue with mom!).
- We give instructions on storing the jam in the fridge. For more detailed info on canning instructions or directions, follow the USDA guidelines.
- This recipe makes about 700ml / 24 fl oz / 3 cups of jam.
Some other ways to enjoy summer a little longer:
Easy Plum Jam
- 2 pounds plums quartered and pitted
- 1 1/2 cups sugar
- 1/4 teaspoon sea salt
- 2 Tablespoons fresh lemon juice
- Place a small plate in the freezer right before cooking the plums (this is to use to check if plum jam is ready).
- Wash the plums and remove any blemishes. Cut the plums in half, remove the pits, and cut the pieces in half again.
- Place a large skillet on medium-high heat. Add the plums, sugar and a 1/4 teaspoon of salt. Using a wooden spoon, stir together to combine. Bring the mixture to a boil and keep stirring until the sugar dissolves. Mash the plums to break them up with the spoon (or a potato masher).
- Add in the lemon juice and keep stirring. Use your spoon to loosen any pieces that stick to the bottom of the pan.
- Lower the heat to a simmer and keep stirring until the bubbles will slow down. As it simmers, skim off any white foam that comes to the surface.
- Be sure to keep stirring for about 15-20 minutes. You’ll know it’s ready when juices thicken like a syrup and when you lift some jam up with your wooden spoon while stirring, it will fall of the spoon in sheets. That's the main sign that the jam is ready.
- Another easy way to check if the jam is ready, remove the small plate from the freezer. Place a teaspoon of jam on the plate. If it sets within a minute, it is ready. If it still appears runny, return the plate to the freezer and continue to cook the plum mixture. Test again in a few minutes.
- When the jam is ready, let it for 5 minutes to allow the fruit to settle
- Carefully spoon the jam into sterilized jars. Leave about 3/4 inch of headroom.
- Let the jars cool completely. Seal tightly with the lids. Label and date the jars. Store in the refrigerator for up to a month. You could freeze for up to year.
