This paste is authentic Green Curry Thai paste. I wish it came in a larger size. I've used most of it already and need to order more. I've used it in numerous styles of green curry dishes from meats to vegan and it always turns out "WOW" delicious!. If you are pondering this, think no further, you won't be sorry with your purchase if you love green curry. I store this in the refrigerator between uses and it has lasted for months without issue.
