I tried this recipe when I saw it in Bon Appetit, and it was great. It's easy to make, takes some time to prepare the sambal ( would say the prep time is more like an hour, with gathering all the ingredients, processing and then simmering the sambal and making the marinade for the shrimp, but the marinade for the shrimp was great. There was plenty of the sambal, too. I put the shrimp on bamboo skewers which I have soaked in water for 30 minutes. I used veined peeled tail-on shrimp which I bought frozen. This was our favorite grilled shrimp recipe of the summer!
