Short answer: you can't. Well, I should say you couldn't!
I recently discovered that Twitter was no longer offering XML as a response format for their API calls. No big deal, XML is clunky, verbose, and I hate every XML library that was ever written. I was ready to move on until a few days later I realized that IFTTT had also pulled Twitter as an input source for recipes. However, RSS was still there; this made the lack of an XML/RSS option from the Twitter folks slightly annoying now.
So I decided I would make one. Normally I would save an idea like this for a hackathon or something but in this case I had a couple recipes I wanted to make ASAP so I figured let's give it a shot.
