Cook Grain with Rocket Stove and a Haybox Cooker - PEP BB food.sand.grain.hay

Here is my submission for the Cook Grain with a Rocket Stove and Haybox Cooker BB - Food Prep & Preservation Aspect - Sand.

For each method, I kept the recipe simple and repeatable:
2 cups of dry rice
4 cups of water
dash or two of salt

Day 3 of BB20 2020: I used a J-Tube Rocket Stove to boil the water then cooked the rice for about 2 minutes before I transferred the pot to the Haybox Cooker.
I am used to cooking rice at a ratio of 1:2 (rice:water) on the stovetop and it worked great in the solar oven too.  For the slower cooking process, the ratio is too high and the rice was mushy - it could be great for a rice porage but not as a side dish (IMO).

To document my completion of this BB, I have posted:
+ a picture of the ingredients
+ a pitcure of the j-tube stove
 - a picture of the grain and water boiling on a rocket stove
 - a picture of your heated uncooked grain being transferred to a haybox cooker (with some sort of watch or timer)
 - a picture of your cooked grain in a haybox cooker (with some sort of watch or timer)
 - a picture showing the final product is at least two cups of grain

Today I used my haybox cooker for the first time. I cooked brown rice.

Everything assembled to cook 2 cups of rice.

I followed the directions in Margaret Mitchell's Fireless Cook Book, substituting bone broth for the water.

Rice simmering on my rocket stove.

Rice pot transferred to haybox cooker.

Mine is made from an old travel cooler and scraps of foam insulation leftover from our pantry upgrade.

Now we wait.

I'm guessing that the directions in the cook book were for white rice, so I cooked mine longer.

Total cooking time was an hour and a half.

Finished amount 0.5 quart or 2 cups.

had the j-tube going today

Made some short grain brown rice.

2 + cups of rice and 4+cups of chicken stock

water gently boiling


Into the blanket cooker!

hopefully this shows more than two cups of cooked rice!

Hi Jordan, that's an interesting J-tube rocket stove! Where can I find more information on it?

thank you. I am not sure what info you want?

It took me about 44 bricks not including the bottom 2 layers.

Some of the bricks had 8 holes in them, some of them had 3 holes in them. They were used flat.

The rest were full red bricks. Some were 3 inches x 8 inches by 2.5 inches. Others were 4 x 9 x 2.5

The feed chamber is 10" tall, the burn tunnel is around 17" and the riser is about 30 inches. or 1:1.5:3

I sifted some local soil here for the mortar. It could have used less water in it.

I did not use a level, as can be seen...

Thank you Jordan. That's already a lot of information. Probably together with the photo that will enable me to build one myself. But if there are design drawings, I would love that.
One question: would it be possible to build a rocket stove of bricks without mortar? Just 'dry-stacking' the bricks?
Or is there a thread somewhere in Permies telling me more on that subject?

There are some more photos in this post Boil Water on a J-Tube

I am not sure of any design drawings myself. However there has to be some out there.  I have just looked at videos of them. Quite a lot of matt walkers youtube videos.

I would say yes it is. It would really help if all of the bricks were the same size. The mortar helps seal off any gaps which suck in air where you do not want it.

I made this stove without mortar, first, and it really did not work well. Once i used the mortar it sealed it up and i could hear the characteristic rocket sound!



There has to be. I would recommend you search for rocket stove. or brick rocket stove. What i made was basically a rocket mass heater core, without all of the insulation/cob/barrel. I am wanting to have an outside kitchen, with rocket stove technology!

1. 2 cups dry rice, 3 cups water, and a little butter boiling on a Vire folding rocket stove.  2. photo of the haybox set up, with a repurposed cardboard box with styrofoam insulation, foil insulation, dry leaves, and kitchen towel (I don't have hay).  3. photo of the pot transfered into the haybox 4. photo of the timer starting (8 seconds in), with more dry leaves on top (not pictured, closing the box lid) 5. photo of the done rice in the haybox just shy of two hours later 6. two cups of rice measured out with plenty to spare.

Here's a photo of the recently boiling on the stove but still uncooked rice, water, butter pot transferred to the haybox before I put the lid on.

Boiled 4 cups of rice for the community on a rocket stove and left it to remain cooking in a hay box cooker. Used 7 cups of water.
