After having some Sainsbury's "extra thick" double cream that was only about the same consistency as normal double cream*, I thought I'd ask for really random food like this that can catch you out, especially if you only have them rarely. And as food is sooo expensive these days it's nice to be forewarned.
*I've since got some from M&S that was as you'd expect. Lidl's was also good.
Any warnings to share?
