I would really like to read some primary sources on Ancient Roman food and cooking instead of just reading random secondary sources from blogs and reenactors. So far I have found Apicius's De re coquinaria, does anyone have any other recommendations? Thank you for your time.
Sure! There's a book of primary source excerpts in English translation that's perfect: John Donahue (ed. and trans.), Food and Drink in Antiquity: Readings from the Graeco-Roman World - A Sourcebook (2015).
