Turn the first squid upside down so that its wings are flat on your chopping
board.
Push in a large knife and leave it inside flat on its side. With a
sharp knife, slice the squid as if you were going to chop it into rings. The
knife that is lying inside the body of the squid will prevent you from cutting
right through it. You end up with a concertina effect with the squid sliced, but
still holding together. Repeat with the other three.
In a pestle and
mortar, bash the fennel seeds into a light powder with a good pinch of salt and
pepper. Sprinkle this all over the squid, making sure it gets into all the cuts
you’ve made. Place immediately on the hottest part of the grill, and grill,
turning every 30 seconds or so or every time it starts to char, until the squids
firm up and turn from opaque to white inside. This shouldn’t take more than a
few minutes.
Add the lemon juice to a bowl with 3 times as much extra
virgin olive oil and whisk together. Stir in the lemon zest, chilli, mint and a
pinch of salt and pepper. Drizzle this over the squid then serve, with lemon
wedges on the side for squeezing over.
