Fortunately, the higher the quality, the less likely it has those. The mustard display at the supermarket has dozens of different brands and mixes. But only one lists mustard seed as the first ingredient, then vinegar and salt, and nothing else. Similarly, hot sauce. And far from the most expensive one, in each case.

Sadly, no salsa lacks them. Or pesto. And, for a short time you could get straight-up pulped avocado, but now it can only be found as "guacamole", with the onions in.
