Neither is wrong, but it depends entirely on the context of what you're talking about. "It tastes good" is present tense; it's something you'd say while you're eating. "It tasted good" is past tense, and you'd say it after you were finished eating.

先 +1S 左边那个表达：这种食物的味道很好吃，但是你只是知道它很好吃或者你希望它很好吃而你并没有尝过。 右边那个表达：这个食物你刚刚尝过，你感觉很好吃。

In a very technical sense, yes, the action happened in the past: B put the pizza in his mouth, chewed it, and swallowed it, and now that is done. But there is still more pizza, right? So he's making a statement about the qualities of the pizza, not about the way the pizza tasted in his mouth at the moment he was eating it.

A: Would you like to try some pizza? B: Mm, it tastes good.In the above example, clearly B has tasted the pizza, I am wondering why B says "It tastes good" rather than "It tastedgood" since the action happened in the past. Or is it because B is stating the present status of the pizza? If so, does "It tastedgood" make sense?
