I put a closed bag of Penzey's bay leaves in a plastic container. I then removed them in favor of peanut butter pretzels from TJ's. I noticed the pretzels had a slight bay leaf taste so I washed out the container with soapy warm water. The bay leaf taste still lingers. I kinda like the taste and will use these bay leaves in everything.( Of course the bag must have 50 leaves!)
As an aside I think the popular spice which you will probably see often is coriander. IMHO!
