For Sunday dinner, we had roast leg of lamb, with the left-overs put in the freezer to make something of, later. Yesterday evening, we decided the 'something', would be a Lancashire hotpot, so we made up and half cooked two, one for later today, the second for the freezer. The first one goes in the oven later today, 30 minutes covered, to heat it through, then 30 minutes uncovered, to brown the sliced potatoes on top of the hotpot.
Lamb, carrots, onions, lamb stock, and sliced potatoes, sprinkled with thyme. We never tried to make it before.
