LOS ANGELES â Miguel Dominguez and his son, Jesse, filled a few trays with pig-shaped puerquitos and football-shaped bolillos, then stuck them in the oven. Back when business was good, they would keep going until stacks and stacks of trays were full of the Mexican breads. On this recent morning, they didnât expect to sell much. The âding dongâ announcing a customerâs arrival came only a handful of times in an hour. Dominguez thought that by now, with the COVID-19 pandemic easing locally, there would be more people coming into Marisol Bakery on Whittier Boulevard in East Los Angeles.
