Blackberry jam

Method

  1. Maceration. Mix the blackberries, sugar and lemon in a heavy-bottomed pot. Cover and leave in a cool place overnight, or at least 3 hours.
  2. Bringing up the temperature. The next day, drain off the juice, bring it to the boil on its own for 5 minutes, then add the fruit: this detour avoids overcooking the flesh.
  3. Cooking. At a rolling boil, high heat, uncovered, 25–35 minutes. Stir, scraping the bottom: blackberries stick quickly.
  4. Skimming. Remove the purple foam with a skimmer in the last five minutes, not before: it re-forms as long as it boils.
  5. Test the set on a chilled saucer, then jar it straight away in clean, well-dried jars filled to 1 cm from the rim, and let them cool standing upright.
