I read about these meatballs a few weeks ago and thought they sounded interesting and delicious. I made them as a part of a pseudo-Thai dinner we had on Sunday night and I am looking forward to serving them again. I'm not going to post the recipe because you can get it over here at Serious Eats.
First off, the sauce is great. It's not too spicy and I think it would be great as a dipping sauce for spring rolls (both fried and fresh). I did not have any scallions on hand so I used very thinly sliced shallots instead.
I also used shallots in the meatballs and they turned out well. (I think these would be really great with ground pork instead). I did not have any Thai basil either, so I wrapped the meatballs in a basil leaf with a little cilantro tucked inside; a very nice substitution indeed.
One other recipe note: we grilled these on a grill rack. The recipe called for skewering the meatballs and putting them right onto the grill, but since they are sorta log-shaped, they spun around the skewer and I felt we'd risk losing them to flames without a grill rack.
