Bullshit, you don't fry stuff in the field or chop up meat or onions, and you cut the carrot into circlels. And you probably won't have those spices with you as well. You just dunk the whole onion then toss it away after cooking. On the last 5 minutes, you empty the can of stewed beef into the brew.
