Rather than the traditional thin soup-like Thai curry called gaeng, this choo chee style curry has the consistency of a 'western' cream sauce. To make the 'zucchini spaghetti,' use a Japanese mandoline. It is not only a great time-saver but it also produces a perfect julienne. To produce a livelier green color in the sauce without making it unbearably hot, puree 1 cup of basil leaves and add it to the simmering curry paste.
