Sumiao Hunan Kitchen in Cambridge will be hosting a special brunch this Sunday they are calling "A Pinch Of Ginger". It is a precursor to one of our favorite food events "A Taste Of Ginger", held annually at the MFA and which we have attended many times. As readers know, diabetes is of special interest due to a strong family history here. You may not know, however, that Asian-Americans are far more likely to suffer from it. We'll be at the brunch to help kick off the gala, one of the first big events of the spring social season. Come and support the initiative while enjoying what looks like a very creative menu.
