Chili Question

I'd try Chinatown if I were you.
On the other hand a mate of mine grows his own chillis and I'm seeing him tomorrow so I'll ask him.
Mmm... do they have to be fresh?

I have found rajas en lata on many occasions. In addition to the ones I have found in Jumbo or Disco (I think unless I am confusing them with the big Coto on Scalabrini Ortiz and Santa Fe), I was in a small shop in Palermo the other day on Humboldt and Nicaragua. They had rajas (en lata), Jiffy peanut butter, among other things that surprised me.

What about Liniers? Have you ever tried there?
