"Cedar," a Lebanese brand, is usually easy to find and very dependable in both orange and rose scents. Perfumey varieties can often be scents designed for soap or candle making that are totaly unsuited for cooking or baking.
Kabul Farms on Parliament has it. You might want to read up on the different kinds, though. I recall that there can be big differences in quality. The one I bought is incredibly perfumey—almost too much.
