Seriously, do you have milk, in your pack?
There's one thread on almond milk, but I am more curious about regular old milk since coffee and breakfast cereal (Spoon Size Shredded Wheat) are two big staples of my hiking diet.
Right now my packing list includes the half-pint box milks but they are terribly heavy, about 10.5 ounces each.
Sugar is an option for coffee. It doesn't cool it down at all, but it does cut the bitterness enough. But cereal would still be a challenge.
