That preservative is borax (also known as E285, sodium tetraborate) - yes, the same compound that can clean your sink or boost laundry detergent. A close cousin, boric acid (E286), sometimes substitutes for it. Caviar makers prize both because they're remarkably effective: they fight bacteria, firm up the delicate roe, and even mellow out that sharp "fishy" taste.
Happy Pride NYC! Truly grateful to have DJ'd in Times Square for NYC Pride. You are the reason I do what I do - and I'm pretty sure we made history with the first caviar bumps in Times Square.
"We always recommend starting with a preset caviar flight, which gives guests the chance to taste and compare several varieties side by side. Itâs a great introduction to the texture and flavor of the different species of caviar."
