Bat Goddess.. I suspect what you had was a type of savory Shortbread. I shall mess about in the kitchen today with some butter, flour, sherry and Pepper and see if I can create something that resembles and tastes similar to what you menitoned.

Of course, this is a year and a half later, so perhaps by now, you've actually found the recipe. However, I won't let that prospect prevent me from making a huge mess in my kitchen. I'll be back.
