To Cook Trout in the Forest
First catch your trout.
Then with a sharp knife split lengthwise along the spine from the inside, cutting from the front while holding the fish on its back on a log, stump or piece of bark.
Salt and pepper plentifully the separated halves on their cut sides, allowing them to remain several hours or over night in a covered pan, then they may be well rolled in flour or cornmeal and dropped, salted side down, into a skillet of hot fat (bear's lard if obtainable), and fried over embers left from a fire of fir or hemlock bark, turning the pieces over after a short time. Do not cover the skillet.
Trout under one-half pound in weight may be similarly treated without splitting.
