I have tried Russian cuisine & I liked it.
Why do we use Past Simple in the "I liked it" part, if
1) there's no indication of when it happened,
2) I liked it at the same time when i tried it, so if we use Present Perfect for "I have tried", then this tense should refer to "I liked" too.
But for no logical reason, I'm sure I should say "I liked it".
Could you please help me explain this usage to my student?
