Prep the aubergines - Slice the aubergines in half lengthways. Score the flesh in a criss‑cross pattern, then drizzle with olive oil and season with salt and pepper. Place cut‑side up on a baking tray.
Roast - Cut the tops off the garlic bulbs, drizzle with a little oil, wrap in foil and place on the same tray. Roast everything at 190°C for 35–40 minutes, until the aubergines are soft and collapsing.
Cool - Remove the tray from the oven and leave the aubergines and garlic to cool until you can handle them comfortably.
Prep the herbs - Finely chop a handful of fresh parsley and set aside.
Scoop & squeeze - Use a spoon to scoop the soft aubergine flesh into a food processor. Squeeze the roasted garlic cloves out of their skins and add them to the processor.
Blend - Add the juice of one lemon, the parsley and the extra‑virgin olive oil. Blend until smooth and creamy. Season with salt and pepper to taste
