While chocolate as we know it didn’t really exist in the Regency, there was a confectioner named Guglielmo Jarrin who created eggs out of rock sugar. He also had a recipe for created transparent hollow eggs of sugar that could then be filled with yellow cream so they resembled real eggs ala Cadbury Crème Eggs. I wish I could have seen these. They sound so cool! But there’s no way I could make them, even if I could find the lead moulds for them. If you want to try, however, you can check out The Italian Confectioner, available in its entirety online at Google Books.
Turtle soup was common on menus in England going back to before the Regency. It had to always be included as a dish for the Lord Mayor’s Banquet in London, and was so popular (and so expensive) that the English even developed Mock Turtle Soup for those who couldn’t afford turtle meat. Mock turtle soup was traditionally made with a calf’s head, so if the idea of eating turtle makes you gag, you might like the mock version even less. Personally, having eaten plenty of it in New Orleans, I enjoy the real thing.
Most people assume that ice didn’t exist in summers during the Regency, but the wealthy did have access to it. Ice houses were big, deep wells where ice harvested from nearby frozen lakes (or sometimes ordered and brought in from the Arctic) was kept through the year. A well-built ice house could keep ice for as long as 18 months, which is pretty amazing. That’s how the famous Gunther’s in London managed to provide ice cream throughout the summers.
The English in our period were quite fond of seafood. My period cookbooks have recipes for such things as smoked fish soup, mackerel pie, fried anchovies, collared eel, and even boiled crayfish (yes, they have crayfish in England). You don’t find recipes for periwinkles and whelks because they were common food for the common people. But they’re mentioned in the famous cookbook by Mrs. Beeton (1861), where she has a table of how much seafood of every type was sold that year in London. Apparently, Londoners ate 4 million whelks (compared to half a million crabs and a million lobsters) and an astonishing 304 million periwinkles!
