Cool sliced cucumber is combined with a homemade spicy hot Szechuan sauce which makes a great side dish or entree.
Hot chilli oil and Chinese black vinegar can be purchased in Asian speciality shops or online.
Whoa, man, I thought I liked spicy food. I cut the peppers back to 4 (considering it also has chili oil), and this was still too hot for me. I really liked the flavor of the dressing, so I will try this one again with 2 peppers, taste, and if necessary, bump up to 3 (maybe, I'm a wimp?). If you REALLY like it hot, go with the way it's written, otherwise, I'd suggest you start out with fewer peppers, and add more to suit your taste. I also think it may be just as easy to add some crushed red pepper flakes instead of "dry-frying" the whole peppers and grinding (with no sacrifice to taste), but just my opinion. - 08 Feb 2015 (Review from Allrecipes UK & Ireland)
