Preheat the oven to 200C and line a baking sheet with parchment paper. Stab the eggplant all over (8-10 times) and place the eggplants, on the prepared baking sheet and bake for about 30 minutes until softened and the skin can be easily removed.
Once cooled, peel off the skin and pound it in a flat based dish with a masher for 3-5 minutes to break down the baked aubergine as much as possible.
