Divide the plums into pieces and remove the stones.
Mix plums, syrup, fresh lemon juice and chili powder in a pan. Heat the mixture while blending. Remove the pan from the heat when the plums have softened.
Chop the liquorice into tiny pieces and blend them with the rest of the mixture. Let the chutney cool and reach room temperature, then place it in the fridge. Serve cold with cheese and biscuits.
Notes
If the plums have very thick skin, you may want to scald them.
