Kitchen notes

This is a refrigerator quick-pickle, not a shelf-stable, canned or validated preservation recipe. The acidity and process have not been tested for ambient storage, and the original source specifies no validated shelf life. Use clean jars, food-grade Hibiscus (Hibiscus rosa-sinensis as identified on the product) and appropriate hygiene; keep chilled. Avoid botanicals to which you are sensitive. No health or medicinal claims are made.
