Here is another thing that readers should be aware of: steel-cut oats require substantially more cooking than the more processed varieties. I buy #10 cans of steel-cut from Honeyville Grain, mostly because I like the taste of this product. Compared to "just add boiling water" instant oats, steel cut is much slower to cook, requiring about 20 minutes of boiling to become sufficiently soft.
As a preparedness food, it requires too much fuel and preparation time to be a first-line food of choice.
On the other hand, a pressure cooker could probably make short work of preparing any of these "semi-processed" commodities, so your mileage may vary. - JN
