&gt; Do Americans think that the flavor of tomato sauce is an additive?<p>Yes. Everything here is an additive. Tomato sauce is &quot;tomato flavored sauce.&quot; Butter is &quot;butter spread.&quot; Etc. A bit of an exaggeration, but when you buy packaged food, look at what it&#x27;s calling itself. If you think you&#x27;re buying NOUN, but the label says NOUN OTHER, then you&#x27;re buying OTHER, with flavor or other essential attribute added that may or may not be based on NOUN.<p>Enjoy your cheese spread.
