For the last year or so I've been in search of a good red salsa picante recipe that would be like the kind you find at a Mexican taco stand -- spicy, fairly thin consistency, but with seeds and small chunks. I'm not talking about Tapatio or one of those homogenous "hot sauces", nor am I talking about American "salsa" of the Old El Paso variety. I've tried a bunch of recipes, some tomato-based, some not, but have never really nailed it. It's possible that the typical salsa picante you get at a taco stand is actually a commercial product but it would be awesome to duplicate it at home.
The attached image is roughly what I'm looking for (the right one, obviously).
Any suggestions or pointers?
