You need
- Blackberries
- 3 kg
- jars, 370 ml
- 7.7
- In all
- 2.9 l
Have 8 ready (jars); the last may be part-filled.
Method
- Rinse the blackberries briefly. If you do not like the seeds, push the jam through a sieve after cooking.
- Mix the fruit with the sugar and lemon juice and leave it for a few hours or overnight to release its juice.
- Cook over a medium heat, stirring and skimming, for 20 to 40 minutes, until a drop of jam on a cold saucer stays put when you tilt it.
- With 2:1 jam sugar four minutes of boiling is enough; use half a kilogram of it per kilogram of fruit instead of ordinary sugar.
- Pour the hot jam into sterilised jars to the brim, close them and turn them upside down for five minutes.
When to make it
Best: August. Possible: July, August, and September.
October: Out of season.
Seasonal calendar →How we count
1 kg (Blackberries) makes about 0.95 l.
Blackberries have no waste; if you sieve out the seeds, count on about 15% less. With half a kilogram of sugar per kilogram of prepared fruit you get about 1.3 kg of jam, and a litre of jam weighs about 1.3 kg: roughly a litre per kilogram of prepared fruit.
