Our first stop in Tijuana is the Mercado Hidalgo, one of the largest central markets in the city, where vendors sell everything from produce and dried goods to cheese and local honey. Javier Plascencia, who helms the restaurants Misión 19 in Tijuana and Romesco in San Diego, says he shops there at least once a week. He always looks for special regional chiles (like Pasillas from Oaxaca), seeds, local honey, Mexican cheeses (he has a cheese cart of only Mexican cheese at Misión 19), clay pots and regional Mexican candies like plantains or yams in syrup.
