The sense of taste is at very heart of dining. Here a woman uses that sense as she evaluates a forkful of pie at a community event. Good? Not so good? I leave the answer to her and to my viewers.
I think she looks away because she wants to think about how it tastes, not how it looks. but then what do I know? Thanks, Alina -- the expression is the whole point here. It looks very judgmental, as it should.
