Put the chicken broth in the pan, add the juice from 3 lemons and top off to about 1/2 inch deep with water if needed. Season the potatoes with salt, pepper, oregano and finely chopped garlic or garlic powder.
Turn the potatoes over and repeat the seasoning. Cut 1/4 cup of shortening into 1/2 by 1/2 inch cubes and distribute evenly amongst the potatoes.
Cover the pan and place in the oven at 375F for about 30 to 40 minutes or until the potatoes are tender inside. Uncover the potatoes and broil for a short while to brown and crisp them as desired. Squeeze a lemon or two over them.
Serves 6 to 8.
