The ongoing excavations at Milton have yielded remarkable discoveries this week to reinforce our understanding of the site. We have been investigating a series of livestock enclosures but have also found many archaeological artefacts, including exquisite tablewares and fragments of vessel glass, predominantly in the western part of the site, which is where we believe part of a Roman villa was located.
The abundance of cattle bones provides compelling evidence for meat production but having also now found more than one whey strainer, it appears dairying was also present. To confirm this, we plan to conduct Organic Residue Analysis (ORA) on these pottery sherds. What we hope to find are traces of lipids (fats), which are the most frequently recovered biomolecules from archaeological sites, because they will not readily dissolve in water. ORA can determine the presence of fats, but also their nature, so it should be possible to determine cow’s milk from other sources.
Whey strainers play a vital role in the dairy process, allowing for the separation of whey, a byproduct of cheese-making, from the curds. This process involved pouring the liquid through the strainer, which featured perforations, fine mesh or muslin clothe to retain the curds while allowing the liquid to pass through. In Roman culture, whey had diverse culinary and medicinal applications. Strained whey, known as “lac whey,” held significant value as an ingredient in cooking, where it was used in the preparation of sauces, soups, and as a base for various dishes. Additionally, whey was consumed as a refreshing beverage and incorporated into medicinal recipes with recognised nutritional benefits.
