Combine vinegar and sugar in a saucepan.
Bring to a boil over medium heat to dissolve the sugar.
Peel the mango and cut the flesh into pieces. Chop onion, garlic, ginger and chili pepper.
Add all ingredients to the pan with the sugar and vinegar and simmer uncovered.
Leave to preserve until all the water has evaporated, stirring occasionally to prevent the chutney from sticking to the bottom of the pan. It can take from 45 minutes to 1 hour, more or less. Remove from heat when the mixture is syrupy.
put it in a jar Keep refrigerated.
I hope this idea will inspire you to prepare canapés or shot glass appetizers.
