The only thing I didn't add was the ginger, and for myself I like to add a lightly scrambled egg to eggplant and rice when finished. It sure is delicious, and the chili gives a bit of heat at the end of each bite. Yum!
I made this last night. Was very very excellent and my boyfriend LOVED it as he enjoys spices immensely. I didn't make the roux into a dark brown colour but had it brown instead, and it was just as delicious (apparently there are different colours of roux and each one has a different thickening power and flavour). Anyway, I used vegetable and fish stock with the prawn shells and added bok choy with the veggies. Very satisfying, will make this again for sure.
