Have you ever wondered how a simple pastry could connect cultures across continents? The humble concha, a Mexican bakery staple, is at the heart of a fascinating culinary journey that spans centuries and oceans. But here’s where it gets even more intriguing: its Chinese counterpart, the bo lo bao, shares a surprisingly intertwined history. Let’s dive into this delicious tale that’s been sparking conversations from Philly to social media feeds everywhere.
In recent years, third culture bakeries have taken the world by storm, becoming a cornerstone of the global bakery boom. Fueled by the rise of the “little treat culture,” these bakeries blend traditions from Asia, the West, the Middle East, and Latin America, creating a melting pot of flavors. Imagine za’atar and shatta finding their way into unexpected pastries, or Japanese matcha becoming a star in both Filipino and Indonesian desserts. These innovations aren’t just about ingredients—they’re love stories baked into every bite, often rooted in the shared experiences of immigrants. And this is the part most people miss: the stories and histories behind these treats are just as trending as the treats themselves.
Take the concha and the bo lo bao, for example. These two pastries, though worlds apart in origin, share a history that predates the current food trends by hundreds of years. Both feature a crackled, cookie-like crust atop a fluffy milk bread base, sometimes filled with cream, jam, or even savory delights like char siu. While the concha is a Mexican bakery icon, the bo lo bao is a dim sum classic, yet their similarities go beyond being mere buns.
The concha, named for its shell-like appearance (or tic-tac-toe pattern when cross-hatched), and the bo lo bao, meaning “pineapple bun” despite containing no pineapple, are united by their unique textures and global appeal. This connection has been a hot topic on social media, especially as people of Chinese heritage explore the origins of their favorite foods. One theory suggests that Chinese immigrants who worked on Mexican railroads in the early 1900s brought the concha back to China, blending it into their own culinary traditions. Another influence? The Portuguese, who ruled Macau and introduced egg tarts to Chinese cuisine, likely played a role in shaping these pastries.
But here’s where it gets controversial: British baker Richard Hart, co-owner of Copenhagen’s Hart Bageri and Mexico City’s Green Rhino, dismissed Mexican bread culture as non-existent on a podcast. His comments ignited a firestorm online, but a quick taste tour of Philly’s bakeries proves him wrong. At Tequilas, pastry chef Jessica Delgado crafts conchas flavored with hoja santa and filled with avocado whipped cream, a perfect end to a hearty meal. Nearby, La Jefa offers jam-filled conchas, ideal for your morning coffee. These aren’t just pastries—they’re pieces of heritage, like Delgado’s childhood memories of helping her uncle deliver bread and earning a concha as payment.
In Mexico City and Philly’s Chinatown, the process of buying these buns is almost identical. Whether you’re at a traditional Mexican bakery or Bread Top House, you’ll use tongs to select your treats from trays. Even Dodo Bakery, with its cozy counter setup, joins the tradition. The secret to their texture? A layer of fat—butter, shortening, or lard—mixed with flour and sugar, topped on the bun before baking. Chinese versions get an extra gloss with an egg yolk brush, and delicate cuts in the dough create that signature crackled crust.
Philly’s dim sum spots like Grand Palace and China Gourmet serve up some of the best bo lo bao, but don’t fill up on siu mai too quickly—save room for these buns! Is it a coincidence, cultural exchange, or something more? The concha and bo lo bao story challenges us to think about how food connects us across borders and time. What’s your take? Do these pastries share more than just a recipe, or is their bond purely culinary? Let’s debate in the comments!
