Armored Turnips
Cut up turnips that have been either boiled or cooked under the ashes.
Likewise do the same with rich cheese, not too ripe. These should be
smaller morsels than the turnips, though. In a pan greased with butter or
liquamen, make a layer of cheese first, then a layer of turnips, and so on,
all the while pouring in spice and some butter, from time to time. This
dish is quickly cooked and should be eaten quickly, too.
