Hi ~ I am making a homemade Salsa Verde for a dinner party tonight that calls for 3-4 jalapeno’s stemmed to taste. You roast them with several ingredients for one hour. My dilemma is that my husband got me Green jalapeno’s and yellow jalapeno’s. I have stemmed and removed the seeds from 3 of the green jalapeno’s, but I am concerned about adding the yellow ones. I want to still roast the yellow ones and be able to add later for taste, so do I leave them whole or just stem them?
