Weeping Harissa Lamb with Boulangere Potatoes

As the weather has turned a bit colder and damper - it seems a good time for a warming roast.

This is an amalgamation of a few of my favourite things, and I think it works really well.

The finished dish does have a bit of heat - nothing too spicy - but a background of heat from the harissa.

The juices from the lamb, and some of the harissa, weep into the potatoes, making for a really rich dish. You will see that no fat is added to the potatoes when the dish is assembled.

All the work is done at the beginning - so its a good dish to do if you are entertaining.

I would serve with something green - just to cut through - as the lamb and the potatoes are quite rich.

I marinated the lamb for a few hours in the harissa - but this probably isn't essential.

For the potatoes it is definitely best to use a mandolin - remember to use the guard!!

1 leg of lamb (2.5 kg ish)

1/2 small can harissa paste 

4 large potatoes - peeled and sliced thinly (use a mandolin)

3 large onions - sliced thinly 

salt and pepper

500 ml chicken stock

1 Make some fine cuts in the leg of lamb. Rub the harissa all over the lamb, and leave to marinate for a couple of hours (if possible)

2 Preheat the oven to 200c.

3 Layer the potatoes and onions in an oven proof dish - which has to be about the same size as the leg of lamb. Season each layer generously with salt and pepper, and finish with a layer of potatoes.

4 Pour over the stock and press down lightly.

5 Put the potatoes in the bottom of the oven, and place the lamb on a small wire rack on the shelf above so that any juices from the lamb will weep into the potatoes. (keeping the lamb on a small rack makes it easier to handle)

6 Leave to roast for 1 1/2 hours. Every half hour press the potatoes down into the cooking liquid.

7 Remove the lamb when cooked to your liking, and rest in a warm place for 10 minutes before carving.
