styrofoam! duh!

i've been puzzling these last couple of weeks about how to shed cooking kit weight.. use a snow peak ~1 L with alcohol stove for 2 people but mainly boil water and make 2 courses.. soup + one bag meal.

was thinking of buying a ti cup to eat the soup out of while boiling more water. but styrofoam is the obvious answer!

however i'm still on the lookout for the lightest cheap pot to boil 0.5 L quickly in on an cat can stove..
