Caramelized Onion

Directions

1. 1
   Slice an onion finely.
2. 2
   Not too finely though.
3. 3
   Toss all of the ingredients into a heavy pan.
4. 4
   Turn it to somewhere around medium-low.
5. 5
   Keep an eye on it for a bit as the butter melts and the onions begin to sweat.
6. 6
   Your only goal here is to cook the onions very gently, stirring every few minutes or so, until they just melt and turn very lightly brown, very slowly.
7. 7
   It's not uncommon to finish with a little vinegar.
8. 8
   just pour in a splash and stir over heat until it's mostly evaporated.
9. 9
   as the onions cook, you can also throw in a little thyme or a chunk of star anise to add even more complexity.
