Runner or Green Beans Foogath

Maybe this was meant to be a main course. It calls for 1kg of beans (I used runner beans) for 4, plus 300g of potatoes. For the beans, at 200g, I thought the pile was more than enough for two. (I usually get 150-200g of green beans as a side for two, but this was a side including potatoes.) The measurement of cumin seeds was way off; I used 1/2 teaspoon for my 200g of beans. Three dried chiles (half of what was asked) made the pretty attention-getting; two would have been better for my 200g of beans. Per the instructions, the potatoes will cook al dente with just a few drops of water. Not at my house. In the end, the dishwas pretty good, but we couldn't eat all I made.
