I didn't score it or egg wash, it rose so high, not sure the picture does it justice. Baked in the big Pullman pan and it's 19cm tall.

Didn't keep good notes but it's this recipe, scaled up for the bigger pan, proportionately a little less butter and sugar than she used. Very nice crumb, delicious toast, I took a slice right from the middle and toasted it for breakfast.
