But his latest project hits a little closer to home.
Southworth, who has lived in Alexandria for 22 years, is releasing A Taste of Alexandria in partnership with Alexandria Living Magazine. The cookbook features more than 50 recipes from local restaurants, with each recipe tied to a moment or theme in Alexandria's history.
Restaurants include The Fish Market, Chop Shop Taco, King & Rye, Mia's Italian Kitchen, Ada's on the River, Junction Bistro and others. The cookbook will come out in November (pre-orders are open here).
Wednesday afternoon, Southworth was featured on Great Day Washington on WUSA9 television, showing off his culinary skills and a recipe for Wagyu Beef Carpaccio from Del Ray Café.
"You might not find a pastry from 1754 or a casserole from 1823, but perhaps an ingredient grown here, a grain that defined us, a nod to international trade enjoyed by our port, or featured creatures once abundant in the Potomac. Each dish is a testament to the traditions, innovations, and global accents that converged to form the Alexandria of today," Southworth writes in the cookbook's introduction.
The foreword to the cookbook was written by Sen. Mark Warner, who noted:
"[Southworth] gives a voice to Black, Brown, immigrant, and female chefs who have always served as the backbone of our culinary industry but have too often been left out of the telling of that story. He deftly ties our revolutionary past to our vibrant, diverse present, and explains how our port proximity has forever flavored our palates with spices brought in from across the globe."
Southworth went to culinary school while working in higher education, but did not want to become a chef. Instead, he became a food-related content creator and has released multiple cookbooks over the years.
