Popular in the 60's and 70's these have gone somewhat out of vogue. Certain foods can be cooked in these terracotta moulds, or bricks, shaped like the food in question. Chicken bricks and fish bricks are the most common. The food item is placed in the lower half so that it fits snugly with a few vegetables.The top half is replaced and the brick is then placed in the oven and the food cooks in its own juices, intensifying the flavour and keeping the meat succulent. It may need to be browned after it is removed from the brick.
