Cook white wine vinegar, water, ginger, chilli, mustard seeds, salt, onion and sugar in a saucepan for approx. 2 - 3 minutes.
Peel the cucumber, cut in half and remove the seeds. Roughly grate with a food processor. Add the grated cucumber to the sauce and cook for about 5 minutes. Stir in the cut dill. Let cool down.
I filled the chutney hot into three small 150 ml jars and immediately closed it with lids.
