I took the path of least resistance and tried the classic "
No-Knead Bread" recipe Mark Bittman popularized years ago. The results in my big Le Crueset dutch oven were decent, but round and pretty flat, in other words, not great for making sandwiches. I tried the same recipe but in a modified loaf pan. Right shape, but really dense and crumbly. I tried over a dozen modifications and none resulted in a "good" sandwich bread.
