Airy, delicate and/or filled loaves (like chocolate swirl brioche)
For delicate loaves you get less wear and tear.
"Since loaves are typically shorter than they are wide, by turning the loaf on its side, you'll have less distance to cover with the sawing motion. That means you'll preserve the integrity of your bread's crumb structure. Too much sawing can mar your slices," she explains.
Tough, crusty bread where it takes a lot of pressure to cut through the top layer
"You'll be able to penetrate both of the toughest parts of the bread - the upper and bottom crusts - right from the start," she says.
"That makes it easier to get thin slices, and it means you won't struggle with detaching the sometimes-tough bottom."
