food verbs

In which scenarios would you use the following verbs differently?

taste food, sample food, test food, try food.

When I would like to taste another person's meal, I would say 'Could I sample your salmon"?

To find out flavors of food, I would use the word taste, "I tasted the banana bread and it's too sweet"

When food is part of an experiment, 'test' is appropriate: "Scientists tested the imported beef for mad cow disease"

When a dish is new to you, 'try' is preferred. 'I tried the dish but it tasted weird'

Is my understanding correct?

Thanks!
