Are you planning on pickling them or using them in a salad? I ask because I grew up on Persian cucumbers (I'm Armenian born in Iran) and I'm curious to know how you prepare them (God knows I've had a thousand variations of prepared Persian cucumbers.. lol).
I was planning to make salad-e-Shirazi with them. I know plenty of places to go for these cucumbers in the San Fernando Valley and in Glendale and even in Orange County, but I was hoping to find a place to buy them in Pasadena. :)
You can also buy Persian cucumbers at most Armenian grocery stores in Glendale. Try Pacific Foods on Pacific just north of Glenoaks or Avakian's on the corner of Glendale Ave and Chevy Chase. I have also seen them sold occasionally at Trader Joe's.
