It's a cooked salsa. Roast or broil your tomatoes, peppers, onions, and
garlic. (texture can be improved by peeling peppers and tomatoes after
roasting.) Then put in a saucepan and simmer with cilantro, lime juice,
salt, pepper, oregano, some blended chipotle in adobo, and cumin. To make it
taste like commercial bottled sauce, add sugar and maybe more salt. Then hit
it with an immersion blender, but not long enough to liquefy the salsa. But
I encourage you to avoid the sugar and see if it isn't better without it.
I don't claim it's going to taste just like Old El Paso. I claim it will
taste better.
If you can get yellow tomatoes, do the above but do not roast or cook
anything, just chop it well. Don't use blended chipotle, it spoils the
color. Just chop a pepper from the can. If it needs less chunky texture,
just mash it up a bit with a potato masher, don't blend. Yellow salsa is
fantastic, mild and sweet at first taste from the yellows followed by a nice
creeping burn. My favorite plan is to grow tabasco peppers and include them
in the middle ripe stage when they are yellow and just on the cusp of going
red. My friends call this stuff "the peach". No peaches necessary. ;-)
