For a while now I've been including an 18th century recipe (usually but
not always French) in a newsletter I do for a mailing list. Now I've
grouped links to a number of them on the main page:

These include entrees from a meal served to Marie-Antoinette, ice cream
recipes from Thomas Jefferson and others, some specific dishes
associated with other major figures, etc. There's also an overview of
the differences between the cuisine of three eras (medieval, 18th
century, modern).
