A "Black Lemon" is an earthy, smoky, spice commonly used in Middle Eastern cooking, and contrary to what the name suggests, is actually a dehydrated lime, but the name of the spice was a mistranslation from Arabic to English ages ago. Despite not having any actual "Black Lemon" in this bitters, the bright and fresh lemon flavor has rich floral notes and deep earthy spices that are reminiscent of the "Black Lemon," hence the name.
