Looks perfectly fine IMO, but culturally I think there's a sense that opaque green liquids are on the wild side. Green slime, radioactive mixes. You know. Anyway, thanks for the link; looks pretty tasty!
I’ve heard some of the others are way more noticeable, like definitely vinegar.
Sounds good. Yeah, vinegar and lemon. Too obvious. IIRC I used nigari (magnesium chloride).
