I'm making a green Thai curry paste from scratch. I'm very happy with the recipe, and I've made it with much success in the past, but today I am cooking for someone who can't take much heat. Or well, only very little; I can put a single capsicum annuum ('standard' red chili pepper?) in a dish for 4, let's say.
But the recipe calls for 3 tablespoons of green bird's eye chilies. That's definitely going to be too hot, even if I de-seed and trim the insides. However, a significant part of the paste comes from these (there's about 11 Tbsp of ingredients in total, so 1/3th to 1/4th is the chilies) and leaving them out entirely probably doesn't do it any favour.
So my question is, what would you replace them with? I could get a green bell pepper, but I imagine that'd be quite watery. I also have access to jalapenos, which are a bit milder (and green, as far as that matters) but I imagine could still get quite spicy. Or perhaps I do leave them out after all. What would you go for?
