I put some blueberries in my 浓情巧克力 milk. What should I do with it now?

Pour it out.

Hmm... Unsalted peanuts, make it a parfait! :D

Remember:

Wtever u combine with 浓情巧克力 have to be ignored, cuz it will equal taste like chocolate

As the Chinese Proverb says

Drink it

This made me smile while 阅读 the question.
I will do this someday... :D
