SUCCESS! (I think.)
I decided that I wanted to do a sandwich bread today because we'll be eating a lot of them over the next few days. My boyfriend is off work for 4 days due to them slowing production and, while I'm sure I'll make us some slightly more involved lunch at least one of the days, we generally eat on the go when he's at home because we're busy cleaning house.
So I decided that this recipe  would be the one to use. It's supposed to have good texture, it has very few ingredients, and the mixing method is what I've been using all along. Instead of the oil I used melted butter, and I used all milk.
Just out of the oven and looking quite tasty.
Now that's the crumb I've been looking for!
I'm so happy with this bread that it's going to be what I use, with a few modifications, for both everyday sandwich bread and hamburger buns.
Oh, and I know the photos are crappy. I'm still working with a cell phone camera instead of a real digital.
