For nearly 14 years, Elizabeth Hernández refused to compromise on how she cooked the Oaxacan dishes she grew up with, even when Arizona kitchens made that stubbornness difficult. That commitment just earned her restaurant, 15 Salsas in Phoenix, a distinction no other restaurant in the city has received: Mexico's Sello M, a government-backed seal recognizing authentic Mexican cuisine served outside the country.
Hernández, a 50-year-old Oaxacan entrepreneur, received the Sello M for 15 Salsas on July 27, according to azcentral.com, making her restaurant the first in Phoenix to earn the designation. The seal is awarded through the Mexican Academy of Gastronomy and Mexico's Ministry of Foreign Affairs, working through diplomatic representations abroad, and it recognizes establishments outside Mexico that promote authentic Mexican cuisine, per the same report. Jorge Mendoza Yescas presented the seal to Hernández in Phoenix on that date, according to a photo caption cited by azcentral.com.
Hernández was born and raised in San Antonino Castillo Velasco, a town about 30 minutes from Oaxaca de Juárez in the state's Central Valleys region, the outlet reports. She left Mexico in 2010 and moved to Chandler, Arizona, carrying recipes that would soon run into a problem familiar to many immigrant cooks: the ingredients she needed simply weren't available locally.
From a Grocery Store Kitchen to a Restaurant of Her Own
In 2012, Hernández began cooking for a grocery store owner before eventually buying the restaurant portion of that business herself, according to azcentral.com. The spot, originally located at the corner of 15th Avenue and Hatcher Road in Phoenix, was then called La 15 y Salsas. She renamed it 15 Salsas and officially opened it on Sept. 1, 2012. The restaurant now operates at 722 W. Hatcher Road, near Seventh Avenue and Hatcher Road.
What set Hernández apart, per the outlet's reporting, was her refusal to Americanize her ingredients or dishes to fit what was easily available in Arizona. She initially relied on people traveling between Oaxaca and Arizona to bring her the products she needed. Eventually, as azcentral.com reports in its Spanish-language coverage, she built her own import business to bring products directly from Mexico, with merchandise entering the United States through California and Nogales.
An Import Business That Now Feeds Other Kitchens
That import venture grew into a store selling the products Hernández once struggled to find, and she now supplies Oaxacan restaurants throughout metro Phoenix, according to the same report. Her businesses generate economic activity and jobs on both sides of the border, the outlet notes. Hernández said preserving authentic Mexican cuisine has been rewarding, and that the Sello M helps celebrate authentic Mexican food, per azcentral.com's reporting.
To earn the seal, a restaurant must have operated for at least two years, maintain a menu based on Mexican recipes that reflect the country's cultural and culinary diversity, use characteristic Mexican ingredients — preferably sourced from Mexico or replaced with local equivalents that preserve a dish's essence — and employ at least one chef or cook trained or experienced in authentic traditional Mexican cooking, according to the Sello M official site. Verification involves both a file review and an on-site visit, and the seal remains valid for two years before requiring a new evaluation for renewal, per the same source.
At 15 Salsas, Sello M evaluators reviewed the recipes and kitchen techniques being used, and Hernández said the visit was meant to check whether the claims in her application were actually being implemented. Mendoza Yescas told Prensa Arizona that the goal is to award the Sello M to at least nine additional Mexican food establishments in the Valley in the coming months, according to Prensa Arizona.
15 Salsas Follows Nogales Restaurant as Second Arizona Winner
15 Salsas is not the first Arizona restaurant to receive the honor. Machi, a Nogales restaurant specializing in Sinaloa-style seafood, became the first establishment in the United States to receive the Sello M in December 2025, azcentral.com reports. The Nogales International described Machi Seafood Restaurant on Grand Avenue as having been recognized with a seal of authenticity from the Mexican government. 15 Salsas has also drawn recognition closer to home — the Phoenix New Times named it the Best Mole selection in its 2023 Best of Phoenix awards.
Beyond the Restaurant: Street Food, a Food Truck and a Festival
Hernández's culinary footprint in Phoenix extends well beyond 15 Salsas. She also opened Lulaá, a North Phoenix concept focused on Oaxacan street food that serves tlayudas, molotes, flautas and tortas; the name Lulaá means Oaxaca in Zapotec, according to azcentral.com's Spanish-language report. In 2025, she received a food truck as a gift and plans to turn it into another culinary venture once she finds a suitable location.
Hernández has also organized the Guelaguetza in Arizona since 2018, an event that has brought Oaxacan music, dance, traditional attire and cuisine to the Desert Botanical Garden and has drawn thousands of people, per the outlet's reporting. Between the restaurant, the import business, Lulaá and the festival, Hernández's work has become a throughline connecting Oaxacan tradition to the Phoenix food scene — one that Mexico's government has now formally recognized.
