**Crispy chili in oil is shown in the ingredients photo. I'm going to go out on a limb and say it is widely available as I have sourced this same product in both Seattle as well as Australia. The brand name is Guiyang Nanming Laoganma . Look for the one that just says Crispy Chili or Crispy Chili Oil. There is a few different kinds available but this one best matched the original dish this takes after.
**For the cabbage as well as the beef you want a really nice char on them. (I would have liked more than pictured but I couldn't get my pan any hotter) This may mean cooking in smaller batches. If you put too much in the pan or wok it gets too crowded and the result is steam cooking which does not produce the results you want.
**Cooking 1 cup of Jasmine rice to 2 cups of water should be enough for this recipe.
