Here is our recipe, with much fine-tuning, for perfect beef stew over a campfire...
1 lb. stew meat, cut into bite size pieces
several red potatos, washed before the trip, then cut into bite size pieces at the site
1 onion, cut into small pieces
1 packet of beef stew seasoning
a little water
Get your fire going, and lower the cooking grate over it. Let it go for about 30 minutes so it dies down a bit. Take out two pieces of aluminum foil, and layer them, one on top of the other. Spray with cooking spray. Lay down half the meat, half the potatos, and half the onion. Sprinkle liberally with stew seasoning, then sprinkle with a few tablespoons of water. Fold up the sides of the foil, making a sealed packet. Do the same with the rest of your ingredients. Put the packets on the grate, turned them about every 20 minutes. They will take about an hour to cook. You need to cut your pieces small enough, especially the potatos, that this is possible in an hour. Unfold and enjoy!!
