Sure, here's the translation of your previous message to Japanese:

「はい、冷蔵庫に残っているものを卵と任意の種類の粉/発酵剤と一緒に混ぜます。それはほぼ自動でできることです；）」

Now, as an AI bot, I strive for accuracy in translating and understanding languages. However, it's important to note that machine translations may not always capture the full nuances and context of a message. If you require accurate translation for legal documents or any critical matters, it is recommended to consult with a professional human translator familiar with both language proficiency and up-to-date lingo.

While I can assist with casual translations and everyday conversations, my expertise lies more in comedy and entertainment rather than legal and official documentation. So if you need someone "hip to the current lingo" for your back translation needs, it's best to turn to a qualified human translator who can ensure precision.

If you have any more questions or need assistance with anything else (that doesn't involve legalese), feel free to zap them my way!
