Mary Berry Plum Jam Ingredients

To make this plum jam recipe Mary Berry way, you will need the following ingredients:

  • 2 kg (4 lb) plums, roughly chopped and stoned
  • 2 kg (4 lb) white granulated sugar
  • 2 tsp ground cinnamon
  • 1 tbsp lemon juice
  • A knob of butter (optional)

Method to Make Mary Berry Plum Jam

Here are the step-by-step instructions for making this plum jam recipe Mary Berry way:

  1. Sterilize the jars and lids that you will use for storing the jam. You can do this by washing them in hot soapy water, rinsing them well, and then placing them in a preheated oven at 140°C (275°F) for 15 minutes. Alternatively, you can boil them in a large pot of water for 10 minutes.
  2. Put the plums in a large preserving pan or a heavy-bottomed pot and add 200 ml (7 fl oz) of water. Bring to a simmer over medium-high heat and cook for about 10 minutes, stirring occasionally, until the plums are soft but not falling apart.
  3. Add the sugar, cinnamon, and lemon juice to the pan and stir gently until the sugar dissolves completely. This may take about 10 minutes. Do not let the mixture boil before the sugar dissolves, as this may cause crystallization.
  4. Increase the heat and bring the mixture to a rolling boil. Cook for about 15 minutes, stirring frequently, until the jam reaches 105°C (221°F) on a sugar thermometer or passes the wrinkle test. To do the wrinkle test, drop a small amount of jam onto a cold plate that has been chilled in the freezer. Wait for a few seconds and then push it with your finger. If it wrinkles slightly on the surface, it is ready. If not, cook for another few minutes and test again.
  5. Remove the pan from the heat and let it rest for 15 minutes to allow the plums to settle evenly in the jam.
  6. If you like, you can add a knob of butter to the jam and stir it well. This will help to reduce any foam or scum that may have formed on top of the jam.
  7. Ladle the hot jam into the sterilized jars, leaving about 1 cm (1/2 inch) of headspace. Wipe the rims of the jars with a damp cloth and seal them with the lids. Turn the jars upside down for 5 minutes, then turn them right side up and let them cool completely.
  8. Label the jars with the name and date of the jam and store them in a cool and dark place for up to a year. Refrigerate the jam after opening and use it within 3 weeks.

Tips for Making the Best Mary Berry Plum Jam:

  • Choice of Plums: Opt for ripe, deep-colored plums with a fragrant scent.
  • Consistent Sizing: Chop plums uniformly for even cooking.
  • Skin Preference: Retain or remove skins based on your taste.
  • Sugar Selection: Employ white granulated sugar for its easy dissolution and radiant hue.
  • Lemon Juice: Introduce lemon juice for flavor balance and improved setting. It also infuses a zesty freshness. Both fresh or bottled variants are suitable.
  • Spice Addition: Cinnamon not only amplifies the plum flavor but also adds a spicy undertone. It comes with health perks like blood sugar regulation. Choose between ground cinnamon or sticks.
  • Cookware: Use a spacious preserving pan or heavy-bottomed pot to prevent sticking or burning. Ensure there’s ample space for boiling.
  • Stirring: Stir gently and regularly with a wooden spoon to prevent sticking.
  • Testing for Doneness: Determine the jam’s readiness using a sugar thermometer or the wrinkle test. Aim for 105°C (221°F) or observe for a slight wrinkle on a test sample placed on a chilled plate.
  • Skimming: Skim off any surface foam or scum for a polished jam appearance.
  • Butter Trick: A dab of butter can counteract foam formation.
  • Sterilization: Sterilize storage jars to keep bacteria at bay. This can be done in an oven at 140°C (275°F) for 15 minutes or boiling for 10 minutes.
  • Filling Jars: Pour hot jam into the still-warm sterilized jars to create a vacuum seal.
