Cote d'agneau: rack of lamb, French style

My Russian colleague suggested we have dinner Sunday night and asked me to pick up some cote d'agneau, or rack of lamb, at a butcher near his house. Four small ribs cost 5,00 EUR or about $6.50: terribly expensive when you consider the price of the rack of lamb that you can buy at Costco!

But still it was really good, and this is how he prepared it.

You sprinkle salt and pepper on both sides of the meat.
Then (this is the key) you smear French mustard on both sides of the meat, and then pan fry it.

The saltiness and sourness of the mustard go well with the meat, and towards the end you can add some minced onions to suck up the lamb juices.

Try this with a couple of boiled potatoes with a slab of butter, salad on the side, and Bordeaux wine? You got yourself a meal for less than 10 EUR a head, much less than what you'd pay in a restaurant.

I'm sorry that I wasn't able to take a photo of it. Maybe next time.
