I have no exact measurements for this bake, just go by feel and estimation.
Baked potatoes in thermal pot. When cooked, peel skin and mashed the potatoes. Add some butter, pepper salt and dried parsley. Mix well and set aside.
I used canned corn beef easily purchased from supermarket. Simply mashed or loose up the beef in a bowl.
Get a ramekin or baking dish, fill the 1st layer with beef followed by a thick layer of mashed potatoes and spread out evenly.
Finally, baked in oven 180c 10 - 20 mins or till cooked.
