Apple and blackberry jam

Method

1. Put a couple of small plates in the freezer ready to test the set of the jam. Peel, core and chop the apples. Sort the blackberries and wash them if necessary. Put the prepared fruit in a heavy-based pan or preserving pan along with the lemon juice, sugar and 200ml water.
2. Cook the fruit over a low heat, stirring from time to time, until the sugar has melted. Turn the heat to medium and simmer until the apples are soft (10-15 minutes). Turn up the heat and boil until the jam tests positive for a set (see Know-how; it should take about 30 minutes). Stir in the thyme leaves and set aside while you prepare the jars.
3. Using a jam funnel if you have one, divide the jam equally among the6 still-hot sterilised jars. Seal with the lids and, once cold, label. Store in a cool place.
