Wash and halve the pears. Bring 1/2 litre water, white wine, 1 tablespoon sugar and lemon juice to the boil. Cook the pears in the stock for about 15 minutes at medium heat. In the meantime, place lemon slices on aluminium foil coated with oil.
Melt the remaining sugar until it is golden brown. Take it off the stove immediately. Dribble 1 teaspoon of this onto each lemon slice. Remove the pears from the stock, drain them and turn them briefly in the caramel with the help of 2 forks.
Arrange on plates with the blackberries and caramelized lemon slices. Spread the rest of the caramel with a spoon in a line (if it is already too firm, warm it up again briefly).
Serve decorated with blackberry leaves.
