What??? Can someone translate this?
I drawn simple diagram. On the left side are top views of the bread, right side are front cut side. A is half of entire bread, like half eaten. Let's say I want half loaf, I cut half of the bread width and then one short perpendicular cut to separate half loaf. That is C view. Now if someone goes after me and they want half loaf, no problem, in E they make red cut and they have they half loaf. But if they want full l…
What you are calling a loaf is actually a "slice". You might cut a loaf into 10 slices, each 10 cm x 10 cm x 2 cm thick. So you the question you are asking is how different people cut a "half slice" of 10 cm x 5 cm x 2 cm. I've never considered cutting a half slice the way you do it.
Personally, if I want a half slice, I would cut it the way you do for a full slice, and then afterward cut it in half while it is laying flat on the cutting board. Then I'd just leave the half slice sitting next to the uncut portion of the loaf.
I'd never cut a half slice the way you show in F, because I almost always want my slices to be the same thickness rather than tapering in thickness from one side to the other. While I wouldn't have cut it the way you do, I prefer your final result.
