This an exotic dish, at least to those less familiar with Thai cooking.
I have yet to apply a difficulty rating to the recipes here but this will not fit the category of 'difficult.' At least to me, it is a whole lot faster and easier to make than our local Nonya Curry Chicken.
If green curry is commonly associated with chicken, red curry seems to go with duck. Both of them are the stars in popular Thai cuisine and this dish is a good way to introduce Thai cuisine to a newcomer. Infuse with the incredible fragrance of Sweet Basil leaves, this dish is a sure winner.
Now, if you intend on roasting your own duck, the difficulty rating will hit the insane level. I do not see why you would want to do that as it plays second fiddle to the curry. And roast duck stalls are aplenty in Singapore. In fact duck is so popular here that there is one that is used to ferry foreigners around.
