As generations pass, towns like Watsonville will become more Americanized, but at the same time some parts of Mexican culture are already weaving into the U.S. fabric, said University of California, Irvine sociologist Susan Brown. She points to salsa, which long ago surpassed ketchup as the nation’s leading condiment. And Brown said American icons like hot dogs and hamburgers are actually the legacy of a wave of more than 5 million German immigrants more than a century ago. “This Mexican wave is a big group,” said Brown, “but we forget that a huge, huge number of Germans came, and we’ve absorbed them.”
