I absolutely love this curry paste. I just got a new shipment of green, red and panang. It lasted from June of 2015. Kept in its bag and original cup in the fridge.  Green is the hottest and all have very distinct  and different flavors. It's easy to whip up a tasty, authentic dinner, usually with cubed chicken and eggplant or zucchini, carrots and bamboo shoots. I like it hot, so I use a good amount. If you don't like spicy, use very sparingly but be prepared for less flavor.  Serve over cooled Jasmine rice
