indicates edible, pleasant, tasty, just OK, appetizing, toothsome, I would not say delicious. Palatable food is acceptable to the palate, something in between mouthwatering and foul. It is NOT inedible, tasteless, or disgusting either. Say peppery and piquant comes to the mind. Others could think of gingery, spicy, hot, fiery, sharp, stinging, pungent or somehow lively and strong. Tasting like pepper, no one would think it mild.
