> If *forced* to use canned tomatoes Well, if it isn't summer you are definitely better off using canned tomatoes than the tasteless fresh ones. >definitely drain them first, and actually, I'd even put them in a strainer and press more liquid >out of them. I always do. The juice can be used for bloody marys or some such. Also, I usually strain out the solids and cook down the liquid over somewhat high heat, and then put back the solids (not just for salsas, but for general sauce thickening as well). That way, you don't over-cook the solids and/or loose taste. >I'd stay away from the 1/2 cup (!) of olive oil Oil (or butter) works fine for thickening sauces based on reduced wine or eqq yolks, but will not help otherwise.
