I have never made soup. I've never closely studied a soup recipe. I'm not even really sure how soup is made (I'm presuming some sort of liquid's involved).
So here's my highly specific request: please give me (or refer me to) one single soup recipe which is:
1. surprisingly simple to make
2. surprisingly delicious
3. able to give me a sense of the fundamentals of soup making
4. flexible - i.e. I can branch out with the recipe to make different sorts of soups.
If you have more general thoughts about soups, that's fine, but please let's keep this particular thread super narrow. Please: only replies which fit all four of the above!
If there's been a similar thread (and I'm imagining there has been, though I've not been able to find it), I'd love a link!
