This essential food made headlines during the first months of quarantine when the internet suddenly became awash with people learning how to make sourdough. While the carb craze of 2020 may be over, baking bread for our enjoyment and wellbeing (both physical and mental) has been around for thousands of years. Now, she’s ready to reveal her findings and her own version of the recreated recipe, which she based on her research on this bread that dates back to the eruption of Mount Vesuvius in 79 AD.  Dust off your starter—it’s time to bake. For starters, there’s the shape of the bread—a round piece that appears to have been imprinted so diners could easily break it into eight triangular sections. She believes this was meant to help the portioning of the bread in a time when serrated knives for this purpose weren’t widely available.  Panis Quadratus also showed evidence of a band wrapped around the outside of each of the loaves. Most experts still don’t know for certain what ancient bakers used it for, but Monaco believes it likely served two purposes: keeping the pieces from spreading during baking in commercial ovens where space was at a premium, and making it easier for porters or bread hawkers to loop loaves onto poles and carry them around town. As for the composition of the bread, it was likely made of common wheat and not spelt, as many historians postulate. Monaco posits the bread may even have contained parsley, fennel, poppy seeds, and Roman Coriander in some markets, a testament to the Romans’ sophisticated style of bread-making and adventurous flavor combinations. Several forthcoming publications to be released starting this winter will fully reveal these findings, including a chapter by Monaco in The Bloomsbury Handbook of Experimental Approaches to Roman Archaeology. Fortunately, you don’t have to wait to make this Pompeiian bread yourself. Alternatively, create a sponge by mixing 65 grams of flour and the same amount of water with a teaspoon of baker’s yeast. Sponges work just as well as starters, and you can make exactly the amount you need using store-bought baker’s yeast. After an hour or two, once the sponge has risen and tripled its size, add it to the recipe as a starter.  Cost: Between $5 and $10 per loaf Level of difficulty: Medium 2. Parch the git seeds. Pour the seeds onto a dry, hot skillet on high heat for a few minutes until the seeds begin to pop. Finish by taking them off the heat. 3. Dissolve your starter or sponge in tepid water. 4. In a bowl, mix your dry ingredients. Make sure the git seeds have cooled down and fold them into the flour. 5. Combine the wet and dry ingredients and knead. Adjust your water and flour content to achieve a firm dough. Your goal is to get a ball that doesn’t stick nor leaves flour behind.  Note: The texture of the flour you use (coarse or fine) may affect the level of hydration of your dough. To solve this, sprinkle a couple of drops of water or a light layer of flour accordingly.  6. Let the dough rest for 2 hours. Leave it in a bowl in a warm, humid place and cover it with a clean, damp cotton tea towel to keep the surface moist. 7. Knead the dough again for 5 to 10 minutes. Sprinkle the salt on the dough as you knead and fold.  8. Let the dough rest for 2 hours. Follow the same instructions as in step 6. 8. Shape the loaf. Rotate and tuck the sides and seams under and towards the center of the dough to make a round cake.   Pro tip: You can use a bench knife or the side of your hand to control the underside of the dough and shape it as you work it.  9. Preheat your oven to 400 degrees Fahrenheit.  10. Let the dough rest and rise again for another hour. This time, place your uncooked loaf on a surface dusted with flour or on the sheet that you will bake it on. Cover the dough with a damp tea towel and leave it in a warm place. Warmth (like that from near a preheating oven) promotes yeast growth.  Note: The dough should be roughly 1.3 kilograms or 2.8 pounds, the equivalent of 4 Roman libre. This is enough to make a modern-age Panis Quadratus that matches several of the archaeological specimens found at Pompeii and Herculaneum. 10. Dust the top of the loaf with flour. 11. Decorate your loaf. Panis Quadratus is famous for its characteristic beltline. Create it by tying twine snuggly around the outside edge of the loaf. Next, mark the eight wedges on the top side of the bread. You can do it by pressing twine, a reed, a skewer, or a chopstick. These are not incisions: Do not use a knife as cutting the loaf causes splitting and further expansion during baking. Finally, create the puncture at the top of the loaf. Use a sharp knife or the tip of your reed and press it into the center of the loaf straight down to the bottom. If using a reed, pivot it back and forth a few times to create a small slit in the dough. 12. Bake for 60 minutes at 400 degrees. 13. Let the loaves rest for about 2 to 3 hours or until completely cool. Serve with sides or condiments that the Romans commonly used, such as salted broth, lentils, stews, milk, olive oil, red wine mixed with water (“You read that right—drinking wine straight in ancient Rome was in very poor form!” says Monaco), ricotta, aged or smoked cheese, figs or dates. She’s not new to this either. Monaco’s specialty is studying ancient food—particularly Greek and Roman—and recreating recipes and narratives to help us better understand not only the culture and civilization of the period but our shared history. That’s the experimental part of experimental archaeology.  “Looking at something in a glass cabinet doesn’t tell you much, but when you’re deconstructing and reconstructing an object, you are able to step into the shoes of the creator and understand the object and its purpose much better,” she says. But it’s not just about the bread. Telling the stories of the people behind it—largely women and slaves, who tend to be invisible in historical records and modern scholarship—are just as important to Monaco. There’s a human connection in every loaf that she wants to bring into focus.
