I don't get any nuances from the wine that I put in my spaghetti sauce. That's why you usually use a cheap cooking wine for it rather than an expensive one. I am not saying that your conclusion is wrong (espresso can indeed be very sweet, that is one of the elements of flavor that makes it so complex), just that I think that the soup is more likely to muddy the waters rather than clarify them. Even putting milk in espresso changes its character. I think adding water, as John said, is the only safe way to make the nuances of the espresso clear.
My espresso do not adhere to the dosing or to the shot-volume constraints usually discussed around, mainly because of the special basket size, the low shower screen and the peculiarity of operation of a direct-lever machine like mine, hence resulting in a drink that is of less volume and, well, is more condensed than a traditional espresso shot. However, what I know for sure from experiment is that the drink I make for my mother, which is an espresso shot poured over water (that is 3 to four times the volume) is much harder for me to "make sense of" than the espresso I drink, which is identical to the shot I usually pour over water for my mother. This is also why I keep telling my mother that she is missing so much by diluting the "thing", and that a delicate property that I can taste in my espresso only turns out into "something acidic" that she -and I, can taste in her diluted drink. So, If I claim that I sense a slight degree of sweetness in my espresso, then I don't see how diluting the espresso with water will make the job easier. Someone in this thread already said that ristrettos are easier to deal with when it comes to tasting sweetness, which I think makes more sense that what you're saying.
Moreover, the reasoning that because espresso is a complex drink; it is made more difficult to sense a particular property in it by pouring it over another complex liquid doesn't hold. This is because I know what lentil's soup is... I know how it tastes... For ages I have been familiar with the sort of a boring, traditional food that one is, so, given that I know very well how each of these two things taste like in separate, mixing them together aids comparison, even if it doesn't aid carrying out a full analysis of the ingredients. Lentil's soup is best when salty, pouring one of my espresso shots over it introduced a lot of bizarre tastes, but most importantly had the effect of adding sugar, which was precisely why it tasted so disgusting.
EDIT: Note that this is totally different from the super-sweet effect Mr. David above is trying to explain, which is something that I read about a couple of times; that some candy-sweet espresso shots are occasionally produced under mysterious circumstances (which is something I find very interesting).
