Simply, it’s Tart - paradise in a Styrofoam bowl. Plain, unadulterated ecstasy, this frozen treat at only 112 calories for a small (157 for a medium) is hardly sinful. It is delicious on its own but can be smothered in coconut, dappled with raspberry, sprinkled with chocolate chips, textured with granola, the choices are endless. But the slightly sour, wonderfully light, frozen indulgence is best on its wicked own.
