I always thought the cans of food weren't too bad, but maybe we were so hungry it just did't matter!
There was a science to eating C rats and liking them. Being a military brat, I had quite a few years of military type of "education" before I got there. A small skillet, preferably teflon coated, a bottel of Tabasco sauce, small container of mustard, a spice mix of garlic powder, chili powder, salt, pepper, onion powder, and some others. For the canned ham you saved your pineapple jelly ration to use as garnishment. The frank and beans, add a good dose of spice mix made it tasty, sort of like chili. Ham and eggs?, the green eggs, heating them along with a canned ham with extra pepper and a littel spice mix really improved the flavor.
The coffee was instant, but us Grunts created a Starbucks version before there was a Starbucks. A canteen cup of water heated with a heat tab, add 4 packages of instant coffee, all the creamer packs you could scrounge and pack of hot the hot chocolate ration. This concoction was enough for 2 people. One of my also carried items was a jar of instant coffee creamer, you could mix it with the grease from the canned ham ration and make a "reasonable facsimile" of creamed gravy to pour over those green ham and eggs rations, just add extra pepper and salt with some of the spice mix.
In Vietnam I was the senior NCO in my Platoon, so whne the chopper came in with our supplies I had the duty of dividing up the rations, but doing it fairly meant I chose just like the Private on the bottom of the pole. It wasn't the meal you got, it was all in the preperation.
