Notes
If you consider yourself a person who doesn’t like the flavor of cilantro. I beg you, just try the recipe with cilantro first. I’m willing to put money on you not even tasting it once it’s combined with all of the other flavors. And remember, sofrito is cooked down with whatever dish you’re making. This is not the raw one-two punch of cilantro that most of you associate with the “soapy” flavor.If you can’t find an heirloom tomato, just use really ripe Roma, Beefsteak or any other standard red tomato.
