Avocados aren’t sweet and contain a lot of fat, so yes, they kind of taste like a butter block with kind of a vegetable undertone. That’s why they are usually eaten seasoned and as a savory.

That said, if they aren’t traditional in your country, they don’t have that much going for them. I like guacamole, but I don’t think the it justifies the price when there are so many other things to eat.
