Moroccan Lamb with Couscous, Aubergines, Courgettes and Harissa

Make the marinade by putting the cumin and coriander seeds in a thick bottomed pan over a high heat, stirring from time to time, until browning and popping and then take off the heat. Peel and roughly chop the garlic, discard and thick rosemary stalks. Put all of this into a food blender.

Pour over eight tablespoonfuls of olive oil, a tablespoonful of fresh lemon juice, teaspoonful of salt and a good grind of black pepper. Blend until it's a reasonable paste. Season the lamb rumps with salt and pepper, rub with the marinade, put in a dish and preferably put in the fridge the night before cooking  Picture  .

The following day take the lamb out of the fridge an hour or so before serving. Prepare the harissa paste  Recipe  . Pour boiling water over the tomatoes, peel and discard the seeds, put into a saucepan over a medium heat with a tablespoonful of olive oil, and mash with a wooden spoon from time to time to produce a thickish sauce. Mix well with a couple of tablespoonfuls of harissa paste to produce a great sauce  Picture  .

Prepare the aubergines and courgettes  Recipe   up to the point of putting in the oven. Top and tail the spring onions, chop into small slices, and put in a bowl along with the couscous.

Brown all over the lamb in a couple of tablespoonfuls of olive oil in an ovenproof pan for a few minutes.

When ready cover with foil and rest for five minutes or so.

Meanwhile put the aubergines and courgettes in the oven. Make the chicken stock and pour over the couscous/spring onion mixture stirring from time to time for about six minutes. If used, dress the rocket with a little dressing - five tablespoonfuls of olive oi to one of lemon juice plus salt.

Slice the lamb rump into thick slices, put on to serving dishes along with the aubergines and courgettes, rocket if used, some couscous, and a spoonful of harissa sauce and serve  Zoom  .
