Domala Oil

Domala oil is named such because it's the byproduct of melting the cheese involved in the pastry. So technically it's pretty much just the fat from the sheep milk all refined out.
  Usually it's just used to fry the pastries in the first place, creating a wonderful little life cycle for it in which every element gets used and you don't have to worry about the pastry tasting like olives or coconut or picking up some other odd flavor out of all of it.
  The weird part is how some people use it to contact aliens.
  I'm not kidding.
  A/n: She's not kidding. She's one of them. I've seen the data and somehow the science tracks but it's real hokey.
  If you pull together more than five ounces of oil coming from your standard domala pastry batch, put it in a fairly flat dish so it's all dispersed, and then expose it to the right resonance frequency, you can send messages to a specific planet in the Cartwheel galaxy.
  It is entirely possible and indeed likely that generations of Veleen and Grozni fortune tellers have been taking advantage of this fact.
  You don't get a good visual transmission this way, but it does serve as a decent baseline to get a dialog started. Mostly you get a rather scratchy voice transmission, with some text. The people on the other end have a similar setup, from what I understand, so it's not exactly talking with highly trained professionals or agents of government. Just people, talking across the universe using food byproducts.
  It's avoided becoming mainstream because a) most people don't talk about it, b) a lot of people dismiss it as akin to the usual fortune teller nonsense, and c) you don't get a ton of revelatory data from the people on the other end so there's less reason to pursue it. This hasn't changed the world. Just given people access to alien recipe collections, in essence.
