Here's an idea I found on the Internet quite a long time ago and never tried--until now.
Get a good thermos. I use a 1L Stanley like you'd see construction workers bring full of coffee.
Fill it full of the hottest tap water you can get and screw the cap on.
Now bring a kettle of water to a boil and get 1 cup of wheat berries.
When the water is boiling, dump out the thermos, add the wheat berries, and top off with the boiling water. Then add the cap and set the thermos on its side overnight.
Eight hours later you should have cooked wheat berries which you can eat with a little brown sugar and milk, some berries, buttermilk, or whatever else you like to have in the morning.
This will be my first taste of thermos cooked wheat berries so I hope it goes well.
I understand you can cook beans and other whole grains using this method too. This would be a great way to prepare a hot breakfast while camping for the cost of the thermos's weight.
I'll have to continue to experiment with this idea if it goes according to plan.
Thanks for reading,
