| Tina, A little late posting but I just noticed your question and have the answer. Hydrolat is normally the "water" or leftover liquid from steam distillation of an essential oil. See link below. So... the question is how literal and accurate was the use of the term in this recipe? If very literal and precise then you have the answer. If it's a generalized use of the term then it could just be a low level witch hazel dilution readily available in the market - I would guess no more than 5-10%.
Hope this helps. |
