class B produce class A dish

This was class B avocado, what's class B?  Not class A.
Class A is supposedly 'Top' quality though not necessary so, but yes you will be definitely paying Top prices.
Fruits and veggies are sold like most things with  a peak/ripe date and an expiry date.
It goes without saying the ripe, ready-to-eat, must-be-devoured-today will be much cheaper than the firmer, less ripe but will be ready to be eaten in the coming days will have a much higher price tag.
TIME in essence is what you are paying for.
