Wash the aubergines, cut in half lengthwise and score the flesh with the point of a knife. Sprinkle with salt, Sirocco spice mix and brush with oil.
Place the aubergines flesh side down on parchment paper and bake in the oven at 200° with a little water.
After 15 minutes, turn the vegetables over, brush with a little more olive oil and leave to bake for another 15 minutes (time may vary according to the size of the aubergines; it is important that the aubergines should be soft but the flesh firm).
Prepare the sauce by mixing all the ingredients.
Serve the aubergines hot or cold with the sauce.
