To explore recipes and remedies further, go to Warwick University’s new Recipes, Remedies, Receipts website for contextual articles and links to online resources (including the Wellcome Library’s fine collection of 16th-19th century recipe manuscripts), plus the chance to share information on your own pre-modern recipe collection, if you are lucky enough to own one! The website is continually being updated, so keep checking back for new articles, links and events.
