James Hemings once prepared lavish dishes for America's founding fathers at Monticello, Thomas Jefferson's Virginia plantation. Though enslaved, he trained in France to become one of colonial America's most accomplished chefs. Now, archaeologists have uncovered the kitchen where Hemings created his elaborate banquets, LiveScience reports.

Researchers at Monticello are conducting a long-term effort, the Mountaintop Project, to restore plantation premises, including slave quarters, to their original appearance. Archaeologists excavated a previously filled-in cellar in the main house's South Pavilion, where they found artifacts like bones, toothbrushes, beads, and shards of glass and ceramics. Underneath layers of dirt, experts also uncovered the kitchen's original brick floor, remnants of a fireplace, and the foundations of four waist-high stew stoves.

"Stew stoves are the historic equivalent of a modern-day stovetop or cooking range," archaeological field researcher manager Crystal Ptacek explains in an online video chronicling the find. Each contained a small hole for hot coals; centuries later, the cellar floor still contains remains of ash and charcoal from blazing fires. Hemings himself would have toiled over these stoves.

During the colonial period, wealthy families had their slaves prepare large, labor-intensive meals. These multi-course feasts required stew stoves for boiling, roasting, and frying. Archaeologists think that Jefferson might have upgraded his kitchen after returning from Paris: Stew stoves were a rarity in North America, but de rigueur for making haute French cuisine.

Hemings traveled with Jefferson to France in the 1780s, where for five years he was trained in the French culinary arts. There, Hemings realized he was technically a free man. He met free black people and also learned he could sue for his freedom under French law, according to NPR.

And yet he returned to the U.S. to cook for Jefferson's family and guests, perhaps because he didn't want to be separated from his family members at Monticello, including his sister, Sally. He later negotiated his freedom from Jefferson and trained his brother Peter as his replacement. Hemings ended up cooking for a tavern keeper in Baltimore, and in 1801, shortly after turning down an offer from now-president Jefferson to be his personal chef, he died by suicide.

"We're thinking that James Hemings must have had ideals and aspirations about his life that could not be realized in his time and place," Susan Stein, senior curator at Monticello, told NPR in 2015. "And those factors probably contributed to his unhappiness and his depression, and ultimately to his death."

Hemings contributed to early America's culinary landscape through dessert recipes like snow eggs and by introducing colonial diners to macaroni and cheese, among other dishes. He also assisted today's historians by completing a 1796 inventory of Monticello's kitchen supplies—and he's probably left further clues in the estate's newly uncovered kitchen, says Gayle Jessup White, Monticello's community engagement officer—and one of James's relatives.

"My great-great-great-grandfather Peter Hemings learned to cook French cuisine from his brother James on this stove," White tells Mental Floss. "It was a spiritual moment for me to walk into the uncovered remains of Monticello's first kitchen, where my ancestors spent much of their lives. This discovery breathes life into the people who lived, worked and died at Monticello, and I hope people connect with their stories."
