In the post linked below, Fatu asked -
"Meanwhile, is there any place I can go in Sonoma County to get middle eastern groceries, like very fine burghal and pomegranate paste and sumac? And good, fresh lamb legs? I'm tired of waiting for my next trip to Berkeley to do any real shopping!"
You've stumped me as far as where to get those groceries, so I've put your question on the top of the board in hopes that someone else can help you.
As far as lamb, are you looking for halal meats? I ask because Real Gyro serves halal. There is an Indian-Pakistani store in Rohnert Park that has fresh halal meats on the weekends but I can't recall the name.
If halal is not a requirement, well, Sonoma County produces top quality lamb. Yet, it can be hard to find at the retail level as most of it goes to fine restaurants. CK Lamb from Healdsburg is excellent - you can ask your grocer to order it for you. Big John's market in Healdsburg usually has a selection of cuts or can order what you want. Other markets that have Niman Ranch or local lamb at various times are Fiesta in Sebastopol, Oliver's in Cotati and Santa Rosa, Glen Ellen and Sonoma Markets in their respective towns, or Martindale's in Santa Rosa. Worth a call.
