Heat some oil on medium heat. Add in shallots and cook for around 3 minutes until they softened a bit.
Add in ginger, coriander powder, mustard seeds, cumin seeds, chili flakes, cinnamon stick and cook for 1 minute until the powdery taste is gone.
Add in mango, raisins, apple vinegar and sugar. Mix everything and bring it to a boil.
Reduce the heat and let it simmer for 1 ½ hour or until the mixture thickens to your desired consistency. Stir now and then to prevent it getting burnt.
Optional: Mash some of the mango chunks to get that mashed texture or simply leave it as it is.
Store in airtight containers and once cooled, keep them in the fridge. This chutney is absolutely delicious together with my baked tandoori chicken. Enjoy!
