You can gain such interesting insights from primary documents, actual
old books and articles and other writing; this is a tiny series from the
1922 collection Kitchen Essays by Agnes Jekyll (the sister-in-law of the famous Gertrude the gardener).
She recommends always having available for breakfast time "a tea caddy which will contain a delicate as well as a pungent blend of tea" and "more than one teapot" of course.
