I make many batches of these and they turn out beautiful and blister-free...but sometimes blistering occurs. I don't know why or how to prevent this from occurring. Any advice and help would be appreciated. Picture included...Thanks!
Let the broiler do all the work, and enjoy the reward: crisp-tender green beans with a kiss of smoky char, juicy tomatoes, and a mellow roasted garlic sauce. Look for slender haricots verts in the prepared produce section of the supermarket.
