ruokake

I’m not finding a widely recognized topic named “ruokake.” Could you provide more context or clarify what it refers to (for example, a cultural practice, place, person, concept in science, or a fictional term)? If you can share a definition or domain, I can draft a concise, neutral wiki-style article under 300 words. If you’d like, I can also create a clearly fictional entry or adapt a similarly named real term.
