My Spanish es malo

Here's the Google translation of what I mistakenly thought was going to be a great salsa recipe:

Ingredients: 2 chopped onions. 3 pickled gherkins. 50 gr. of butter. 4 tablespoons of vinegar. 4 tablespoons white wine. 6 tablespoons of tomato sauce. 1 minced cayenne. Parsley. Sal

Preparation: Put the chopped onion in a saucepan with vinegar and white wine. Cook over low heat until the liquid is consumed by half. Add chopped pickles, tomato sauce, the cayenne and salt. Let bake 10 minutes more. Add the parsley and butter, stir. Served to accompany grilled meats or grilled.

First of all, Google translations are icky. Secondly, darn. I don't think this is what I'm after.

On the upside, after surfing some more, I have found out that what I'm seeking is probably salsa roja. As opposed to salsa cruda or fresca or salsa verde.

Wikipedia says salsa roja is made with cooked tomatoes, chiles, onion, garlic, and cilantro. But elsewhere, I am reading that salsa roja is made by toasting dried red chiles, then putting them through a blender with garlic.

The quest to learn how to make salsa roja (if that is indeed the yummy stuff served by taco trucks) continues...
