The pan in the second picture is what I use to make the 'poppabear' Chilimac in. For just one of those pans you would need about 2.7 kilos of macaroni, cooked and put into the pan, add 1.7 liters of ketchup, and two #10 cans of 'chili no beans'. The US #10 can is 18 cm high and 15.5 cm in diameter which usually holds 115 US ounces or about 3.4 liters. Stir well then put in the top of the oven until it starts to bubble around the edges. Then sprinkle 1 kilo of grated (we use mild cheddar) cheese over the top and continue to cook till the cheese has melted, then serve! Should be enough for 35-40 adults, or 10 teenage boys. If you make your own chili, you can vary the ingredients to suit your own taste. There should be a chili recipe in the TM 10-412 if you cannot purchase already made cans, should be in Section L (page 30 of the full index), item L 028 02.
