STORAGE: The flavour of aubergine bhaji develops with time, so this makes it a great candidate for cooking ahead. Store it in an airtight container in the fridge or freezer, making sure to cool it to room temperature first. To reheat, tip it into a pan over a medium heat, and warm through until simmering. Alternatively, you can pop it in the microwave for a couple of minutes until it’s piping hot through. From frozen, defrost it in the fridge overnight or for a few hours on the counter first.
