Americans are dabbling more and more with ethnic cuisines, says a survey by the National Restaurant Association. It says one-third of consumers tried a new cuisine in the past year and two-thirds eat a wider variety of ethnic foods than they did five years ago. The association’s Annika Stensson says, “The typical consumer today is becoming more adventurous and sophisticated when it comes to different cuisines and flavors.” Some cuisines are so familiar they barely register as ethnic. The survey found 80 percent of consumers eat at least one ethnic cuisine each month; 17 percent eat seven or more in a month. The most common ethnic cuisines are Italian, Mexican and Chinese. Least known – Ethiopian, Brazilian and Korean.
