To cook a soup or stew in a haybox, prepare all the ingredients, bring the pot to a full rolling boil, boil it hard for 10 to 15 minutes (longer if the meat is raw) and then seal it in the box for 3 to 6 hours. Root vegetables soften and meat falls off the bone, but a large meat stew held warm is where bacteria that survive boiling are most likely to grow, so keep the hold short and reheat to a full boil if there is doubt.
Part of Retained Heat Cooking
Stews are the box’s best use, since a big pot of dense food holds heat, and also its biggest risk, since the same pot cools slowly through the bacterial growth range.
Method
Step 1: Prepare. Chop everything, with meat in pieces small enough to boil through.
Step 2: Boil. Bring all ingredients to a full rolling boil. Boil for 10 to 15 minutes, and longer for raw meat.
Step 3: Seal. Move the pot into the pre-assembled box at once and close it.
Step 4: Hold. 3 to 6 hours, never past 8.
Step 5: Finish. Season after haybox cooking, because long cooking dulls herbs and spices. If the stew is cooler than you expect, or has been held more than 6 hours, bring it back to a full boil before serving.
Why Meat Stews Need Care
Heat-resistant bacterial spores such as those of Clostridium perfringens survive boiling and grow quickly in large, slowly cooled meat dishes between roughly 4 and 60 degrees. That organism and its behaviour come from standard food-safety references, not from the overview, which says only that meat must reach a full boil and stay above 60 degrees. A bigger pot cools more slowly, which helps the hold but makes any cooling that does happen slower through the growth range.
Common Mistakes
- Adding raw meat late. Boil it in from the start.
- Opening the box repeatedly to taste.
- Leaving the stew in the box once it has cooled below hot.
Safety
Scalds and slow cooling
Large stew pots are heavy and splash; lift with both hands and keep children clear. Any stew that was in the 4 to 60 degree range for hours should be discarded if it smells off, even if it can be reboiled.
