Question

How do you say, "Can you cook Japanese food?" in Japanese?

Answer 1

日本料理を作れますか？
にほんりょうりをつきれますか？
nihon ryouri wo tsukuremasu ka ?

Explanation:

Japanese food is 日本料理（にほんりょうり）
The verb "to make" is 作る（つくる）
By putting the verb in the potential form（つくる　ー＞　つくれる） and using を (wo) as a direct object marker, one can ask the above question.

I don't think this is English grammar, but I couldn't resist answering.
