What was the Professor teaching his colleagues in the cook house?
No, Private Quelch did not change even after being assigned permanently to cook house duties. There also, he showed his intelligence in cooking methods. He even gave a lecture to the other cooks on how vitamin values were lost by peeling potatoes. This shows that old habits die hard.
