Check out the photo’ed book of receipts on the cooking blog. It’s a photographed pdf. of a book of receipts written in 1731. The book is housed at the Va Tech library. The handwriting is beautiful; makes mine look—- well, we won’t go there!
I added it as a primary source link on that site as well in case someone wants to print it out or copy out receipts. The receipts towards the end of the book look like they could have been added later. All together, it’s a beauty!
