Sorry, think you misunderstood my post. Milder in parenthesis following red. Salsa fresca has very few ingredients and I think you should have a taste of all for a balanced flavor. My preference is white onion; it's clean and relatively mild. Pretty sure white onion is the common choice as well for mexican dishes and condiments, so I'm not alone. <img src="http://www.traveltalkonline.com/forums/images/graemlins/Wink.gif" alt="" />
