Ingredients You’ll Need

Making this jam is straightforward, and quality ingredients make all the difference. Here’s what you’ll need for a full batch:

Main Ingredients

• 2½ lbs ripe plums, halved and pitted
  Ripe plums give the jam a deep color and natural sweetness.

• 4 cups granulated sugar
  Provides sweetness and helps the jam set.

• 2 tbsp lemon juice
  Helps the jam gel and adds a bright flavor.

• ½ cup water
  Softens the plums during cooking.

Optional Flavor Enhancers

• ½ tsp vanilla extract – adds warmth and depth

• 1 cinnamon stick – perfect for a cozy, autumnal twist

Substitutions & Ingredient Prep

Ingredient Substitutions

• Brown sugar can replace white sugar for a richer, caramel flavor.

• Frozen plums work fine, but thaw them first and remove excess liquid.

• Low-sugar variation: reduce sugar by up to 25%, but the jam will be softer.

Dietary Adjustments

• This recipe is naturally vegan, gluten-free, and dairy-free.

• For a keto-friendly version, use a keto sweetener, though it may not set as firmly.

Ingredient Prep Tips

• Wash plums thoroughly to remove dirt and residues.

• Remove pits and cut plums into halves or quarters.

• For smoother jam, chop plums into smaller pieces.

• Measure all ingredients before starting to make cooking easier.

Step-by-Step Instructions

Follow these steps for perfect Mary Berry Plum Jam Recipe results:

Step 1 – Prep the Plums

Wash and halve the plums. Remove the pits. Place them in a large, heavy-bottomed pot with ½ cup water. The heavy pot ensures even cooking and prevents burning.

Step 2 – Cook the Fruit

Cook plums over medium heat for 10–15 minutes until they soften. Stir occasionally to prevent sticking. You’ll notice the plums releasing their juice and starting to break down into a chunky mixture.

Step 3 – Add Sugar and Lemon Juice

Add sugar and lemon juice to the softened plums. Stir until the sugar completely dissolves. The mixture should look glossy and begin to thicken slightly.

Step 4 – Boil and Thicken

Bring the jam to a full boil. Reduce heat slightly and continue to cook for 20–30 minutes, stirring frequently. The jam will gradually thicken and develop a rich, deep color.

Pro Tip: Slow cooking preserves the flavor and prevents burning. Do not rush this stage.

Step 5 – Test the Set

Use the cold plate method: drop a small spoonful of hot jam onto a chilled plate. Wait 10 seconds and push gently. If it wrinkles, it’s ready. If not, cook for a few more minutes and test again.

Step 6 – Finish and Jar

Turn off the heat. Remove the cinnamon stick if used. Spoon the hot jam into sterilized jars and seal tightly. Let the jam cool completely before storing.

Serving Tips:

• Spread on toast, scones, or bagels

• Stir into yogurt or oatmeal

• Use as a filling for cakes, tarts, or pastries

• Serve with cheese or charcuterie boards

Health Benefits of Homemade Plum Jam

While indulgent, homemade plum jam retains some nutritional benefits:

• Rich in vitamin C and antioxidants

• Contains dietary fiber from the fruit

• Free from artificial preservatives found in commercial jams

Homemade jam is a healthier choice, giving you control over sugar levels and flavor additives.
