The Hay Box - Insulated Box Food Cooking
http://www.moscowfood.coop/archive/hay_box.html
by Mike Forbes, from the April 2001 Newsletter Several years ago a professor introduced me to the idea that when you cook food, much of the energy from your stove is used to overcome heat loss from your food to the kitchen air. If we can insulate our food so heat isn't lost as rapidly, then wouldn't it then take less energy to cook it? Using rice as an example, theoretically once you boil the rice the heat energy to cook the rice completely is there. The heat leaves the rice because the food is insulated poorly, so we overcome this loss by turning the burner down low and simmering it for 30-40 minutes. Couldn't we boil the rice, remove it from the heat source and immediately put it in an insulated box where the heat energy couldn't escape and would finish cooking the rice? Yes, we could and it does work, almost. The catch is building a perfect box that no heat can escape from. I haven't been able to do it and I doubt many scientists can do it in the lab. What I've done for the past 7 years is build various insulated boxes that do really well. I use them primarily for cooking grains like millet, groats, and quinoa and for keeping food and water warm for a LONG period of time. The trick is to build a box that has as little air in it as possible since air is a poor storage medium for heat. I built my box to the exact size of my large cookpot. The boxes are built from rigid foam insulation with a radiant barrier (shiny aluminum coating toward the inside). I glue them together with hobby glue or foam adhesive. (Liquid Nails makes a low-toxic foam adhesive available at many hardware stores). I put little strips of wood on the inside bottom to keep the hot pots directly off the insulation. The door is just a rectangle of foam that fits into the box. It is critical to make the door fit tightly. If you put a slight bevel to the door, it will create a much better seal. Using a table saw to make your cuts makes the process very easy and accurate. To cover the ugly shiny insulation box, I built a wood box around it and lined the door seal with flexible wood strips or duct tape. If you build the box to your largest pot you can still use smaller pots with good success if you add more thermal mass to the box. I found that filling small pint jars with hot water from the tap works well to eliminate any air spaces in the box. My boxes have been only 2" thick (R-14) and work very well. If I put a pot of hot food into it I can pull it out 2-4 hours later still piping hot. That makes cooking food for many people a lot easier. I would imagine that if you made the box 4" thick and sealed it really well the efficiency would be outstanding. It is my understanding that this concept is old and that traditionally hay was used in the boxes as insulation, hence the name hay box. |

Sounds a lot like Thermos cooking. Check out this Kurt Saxon article:

After Action Report - NUTS! vs. Thermos
I thought the Thermos idea was so cool that I had to try it. I went and picked up a cheap ArcoSteel Vacuum Insulated stainless steel thermos for $8-- thanks to the trade deficit with China. Not wanting to buy a bulk bag from a Feed store if this didn't work, I went and grabbed a half pound from a health food store. Costs about 5x as much as bulk from a feed store, but it was still only about 70 cents. The Thermos was 1.5 pints and everything I read on Thermos cooking for wheat berries says to use 1/3 wheat berries and then fill with boiling water. So a cup of wheat went into the thermos. Then I poured in boiling water from the kettle and quickly sealed it. I had some fun shaking it a bit and then laid it on it's side. It didn't do anything. It dawned on me that I had just reached the boring part of the experiment, so I walked away. 5 hours later, I opened it up. I got a few fluid ounces of brown "wheat tea" that actually tasted quite good. The wheat berries themselves had swolen to fill up the thermos. I poured them out and tried them. Slightly chewy, but thoroughly cooked. It worked perfectly. I ate my fill and then put the rest in an old yogurt container for tommorow. It looks like each "cooking" will produce enough for 2 or 3 breakfasts in my .75 quart Thermos. The full quart sized ones like is discussed above will likely make even more. Excellent tip! Now I can store wheat and have a means of cooking it without getting a mill. If I can boil water just until it boils, I can cook it in my thermos without wasting any excess water or heat. Thanks so much for starting this topic zhukher and thanks for the info on Thermos cooking R. MacDonald!:clap2: |
Re: The Hay Box - Insulated Box Food Cooking
If you're stocking wheat berries, you might as well know how to sprout them. This is a very quick guide to sprouting several grains and legumes. If you soak grains or beans overnight before cooking, they will cook faster, and will have more nutritional value.
-BJG ******************************* http://www.efn.org/~sundance/Sprouting.html Sprouting 101 - No prerequisites required The foundation of the living foods concept is the seed. Filled with nutrients needed by the growing plant, and suffused with vital enzymes, seeds are the very core of life. All the energy and life of a plant goes toward making seeds. Each seed holds vitamins, minerals, proteins, fats, and carbohydrates in reserve, awaiting the suitable environment to begin growing. When air, water, and a suitable temperature are provided, a miracle begins. The seed germinates,begins to sprout, and an incredible flow of energy is released. Natural chemical changes occur. Enzymes are produced to convert the concentrated nutrients into those needed by the growing plant. As the sprouting process continues, carbohydrates are made easier to assimilate. Complex proteins are converted into more simple amino acids and fats are changed into fatty acids, which are easily digested soluble compounds. Vitamin C, along with some other vitamins found only in trace amounts in the seed, is produced in larger amounts during sprouting. In addition, sprouts absorb minerals and vital trace elements from the water used to grow and rinse them. Moreover, the minerals in sprouts are chelated; that is, in their natural state, they are chemically bound to amino acids, so that they are easily assimilated by the human body. Sprouts which turn green are rich in chlorophyll. http://www.efn.org/%7Esundance/rainline.gif Sprouting Advantages

Re: The Hay Box - Insulated Box Food Cooking
Remember with any jar with a lid with holes in it, and some seeds, you have a greenhouse that you can carry in a backpack if need be. Just add water!

I know it's just laziness but after doing some google seaching for thermos cooking, more sites/forum posts on the net said they put the wheat berries in cold and just added boiling water from the kettle. My guess is that boiling them together would cook the wheat berries more thoroughly and they'd be less chewy. Perhaps I should do some testing. Figure out how much energy it takes to get the water and berries boiling together in a pot versus my stove top kettle. My guess is that the kettle is more efficient, but overall the heat going into the vacuum flast is probably greater when you boil the wheat berries. The real test will be when I cook lentils and rice. It's possible that the cold grain and kettle method won't give sufficient heat to cook it all the way through like the wheat berries. Perhaps they'll be "crunchy" still because of the loss of heat from cold berries. I'll play with it some more and figure it out. Vacuum Flask cooking seems like it could be the cornerstone of a low energy use/low water use diet during times of trouble and I think it's worth testing. |
Re: The Hay Box - Insulated Box Food Cooking
Does anyone know of a vacuum flask kettle? I think that would be awesome. The bottom would be conductive and non vacuum (as that's where the heat goes in) but the top and sides would be entirely vacuum insulated. The spout would be short and would have a vacuum insulated cap and an ever so tiny hole with one of those steam noise makers to let you know it's done.
I suppose it might explode though. |

Re: The Hay Box - Insulated Box Food Cooking
Rice was steaming hot 4 hours later, but slighlty undercooked. Pretty good consistency, but had a slight smell & taste of raw rice. I figure that a lot of heat was lost when I was struggling to get all the rice in the thermos. I put it back in the pot, brought it up to a boil again, and threw it back in the thermos. Breakfast.
I am not discouraged. Onward! :ridinghor Also just dusted off my sprouting jar and put some alfalfa in to soak. |
Re: The Hay Box - Insulated Box Food Cooking
Glass thermos seems to work for me. Wouldn't it be easier to put raw rice in thermos and just add boiling water though? That way funnel is not needed.

Re: The Hay Box - Insulated Box Food Cooking
I wasnt even going to read the thread,thought 'I dont need this'
I was wrong,great ideas here.I had read of thermos cooking before,but lost the knowledge in this old brain somewhere.Going to have to try the chicken. And this plays right into my dehydration experimentation,bet this is excellent for rehydration,I will try this next week when I have the time.Also like that upholstered box. EXCELLENT THREAD folks! Spuds:sheep: |
Re: The Hay Box - Insulated Box Food Cooking
Well, since my first test, half of all my meals have become thermos cooked. My friends and co-workers think it's a bit nuts after I explain. Before I explain, they think I just brought lunch in a thermos.
I've been trying pretty much everything I could get my hands on. Some things that worked better than others: Pretty much all grains. Rice, lentils, wheat berries, bulgur wheat, kamut, barley, and so on. They all worked great. The rice and lentils were best after I left them for 8+ hours rather than 4 or 5. Eggs. Maybe there's something else I could mix in there, but the texture wasn't exactly pleasing. When I tried mixing in some grains, it didn't really help. More experimenting is definitely needed. Maybe I need to adjust the water:egg ratio. They're cooked, but not exactly pleasant. Sort of like poached eggs gone wrong. Veggies. Fresh & Dehydrated. Both worked great. The fresh veggies get cooked/steamed in a very short amount of time (some as low as 1-5 minutes). Potatoes. Absolutely amazing. I filled half the thermos with cut potatoe chunks and 5 hours later they were perfectly cooked. Can't say I'm a fan of the starchy left over water though. I have not yet ventured into cooking meats other than eggs. I want to do some more reading on that first. |

Re: The Hay Box - Insulated Box Food Cooking
Wow
I thought from the title of the thread , how useless is this? I was wrong, Thanks for starting the thread. It has showed me a better way to do things, I was already doing Turtleguy9 |
