Good question.

Are you thinking of mixing it in the peanut butter, cooking it, then spreading it on the cracker?

The recipe said to not let the herb be exposed. In other words, it needs to be covered with peanut butter completely.

So, if it is mixed in it would be exposed to a degree.

I have been enjoying my firecrackers. I quit smoking.

I will try it if I understand how you would prepare it.
