That's a good recipe IMO. If going for the green version from fresh chilis, cardamom is not usually used. I'd also suggest to include at least some part jalapeño or a similar grassy chili.
The red version can be made with dried red chilis as instructed, cardamom included.
I'll also give a mention for "filfel chuma", a less common but delicious spicy condiment.
