I've used both homemade and bottled Chinese chilli oil for Chinese cooking, and I don't think it would be hot enough for you.? Besides, curries are usually oily enough without adding more oil!

? It's often made by heating oil with dried chillies -- whole, or flakes, or even powdered -- almost to the smoking point, then letting it sit, and finally straining it.? It becomes a nice red color.? If you do buy some, note that many brands contain some sesame oil, and that would give a definite non-curry flavor.
