Haybox (aka Thermal) Cooking

I’m always on the lookout for methods of alternative cooking, so I was quite intrigued when I learned about the haybox cooker. I was also surprised that this new-to-me idea is actually a very old method of cooking! Haybox cookers (also spelled hay box) are sometimes referred to as wonder boxes, fireless cookers, or thermal cookers. They cook food by using retained heat. In other words, the food is partially cooked first, then allowed to finish cooking in an insulated container.

Early haybox cookers were wooden boxes which used hay as insulation. People still use hay, but wool fleece is popular too. The box itself can be anything from wood to a thermal bag. They tend to be susceptible to moisture build-up, so probably the only thing that wouldn’t last long would be cardboard. Dan made my haybox from an old travel cooler and leftover foam board from our pantry insulation project.

I bought this little camping stove years ago and can no longer find the website. So much more convenient than campfire cooking, although it constantly has to be fed to keep it going. That’s why it pairs nicely with the haybox cooker!

Then I covered it up, closed the lid and waited. It’s hard not to peek, but every time the cooker is opened heat is lost, so it’s best not to open it if at all possible.
