It's very bitter—

But also sweet,

You'll be a quitter

Tasting raw and complete,

Otherwise, it's quite the treat.

Through and through,

Rich mixes with deep,

But light hue

In the taste will creep,

Just let the flavor seep.

Varieties have no number,

Snow, chestnut,

and umber,

No matter what,

It's a delicious cut.

Prompt: To describe something.
