Tamarind Soup using something called Laos
I have a Chinese/Asian cookbook and the above soup calls for something called Laos (it calls for 1 inch, peeled and sliced). I can't find anything on it, the internet searches just come up with the country or the cuisine of the country. Does anyone know what it is, or is it just a typo in the book? The cookbook is The Ultimate Chinese & Asian Cookbook by Hermes House. Thank you!!
