Went to Los Angeles for Christmas with our daughter's family.We wanted to make an old fashioned dinner.We could not find turnip-bought rutabagas instead-what is the difference? Also could not find fresh or frozen butternut squash.Also jars of boiled onions or frozen pearl onions were not available. The dinner turned out great-but we did not realize that some items would be not available! Are any other products just regional? We tried Whole Foods-Trader Joes-and Ralphs!
