I use a canvas haversack - much like Spence's but it has three buttons - lined with an old towel. I rinse out the towel after a hunt.
Always handy to have a towel.
Pick a good spot near a creek and start your fire.
For skinning I put a 1" slit just ahead of the tail. Twist my finger in to open an air-space between the meat and hide, then hook two fingers on each side of the slit and pull. Then I work the upper half off like a seater, slicing the head and fore feet off with the skin still inverted over then, and do the rear feet and tail the same way at the other end. I confess to carrying a HD pair of game shears for the feet, tail and head. Makes it fast & easy. Then I slit the belly and pull out the guts, lungs and heart. Ready for the spit.
Now, stop at the stream, rinse off your hands, and fill your boiling pot and set it on a stick over the fire. Trim a green sapling with a point on one end and a couple "Y" sticks and run the sapling through the squirrel. Use a couple sticks from the sapling to hold the legs back against the sapling to keep them from burning before the thighs are done. Set the spitted squirrel across the "Y" sticks and torn every minute or so.
When the water boils put a 1/4 cup of rice in a cup and pour the boiling water in and cover (you can set it on a flat rock beside the fire - and that towel makes a GREAT hot mitt). Put a teaspoon of gunpowder tea in a bamboo strainer and pour the rest of the water through it into a cup or mug and then allow it to steep a couple minutes - don't forget to turn the squirrel.
After a couple minutes add any flavorings you're lucky enough to have to the rice: parched corn, dried beef, jerkey, dried cherries or a slice of None Such Mincemeat (PC Pemmician - as in "Price Chopper". Be sure to use the dry variety). Let it sit a minute or two to reconstitute and the flavors be absorbed by the rice.
Now sit back and have a feast. And top it all off with a pipe full o' tabac for desert. Oh, and sit on that folded up towel from up top to keep your caboose dry. :grin:
By the way - this has been my squirrel hunting routine since THE ADMIRAL decided we had arrived at well enough off and it was no longer necessary for me to bring home squirrels for food. :haha:
