Well I have a recipe that specifically says dried lavendar leaves but all the others I have seen ...
just say "lavendar". So if purchased in the spice dept they are the dried blossoms? That's good to know. I only remember seeing the dried blossoms sold but that was for potpuri use. I have had a grilled shrimp appetizer where dried lavendar leaves were used in a citrus marinade. Comparable to use of rosemary but with a different taste (but good!)
