I do have a pasta maker at home. My noodles are based on the German spatzel recipe which is a 4 eggs mixed with 3 cups of flour (I mix white with different whole grains) and enough water to make a dough consistent with pasta making. However, I just want to add how I cook pasta in the field which I have only done with packaged spaghetti noodles so far:
First, I preheat 500 ml of water in my Nalgene "solar cooker" which I presented elsewhere in the Forums:

This has gotten the water up to 110 deg F on a warm July day. Then I boil the pre-heated water in an "Energy" can on my Altoids alcohol stove, break a box of spaghetti noodles in two and add one half into the Nalgene bottle. I add enough boiled water to cover the noodles, screw the lid on, and wrap the bottle in a Reflectix cozy that has Velcro attached:

It cooks for 20 minutes. I also usually add boullion to the noodles before immersing in boiling water.
