The star of the Chicken Balsamique Sandwich at m.henrietta ($9.95) in Edgewater is the tamarind balsamic syrup. Its sweet yet very savory flavor pervades the sandwich, balancing the dollop of very creamy goat cheese, allowing it to add a nice bite to the sandwich without overpowering everything else.
The sandwich also sports a cherry tomato and golden raisin relish that adds a shot of mild sweetness and a hint of vinegar. Unfortunately, the slightly dry herbed chicken plays a bit of a background role, as it seems to be there mainly for substance. But because of the flavors of the rest of the dish, that's not a huge problem.
