This recipe from Gourmet Magazine is an example of what one can expect to be served at a Spanish tapas bar. They are very quick to prepare and can be made up to one day in advance, keeping in mind that they should be brought to room temperature before serving. I only use 1/2 teaspoon of red pepper flakes but you can use a whole teaspoon if you like your food spicy.
This Peanut Butter Nanaimo Bar (Canada) recipe contains graham cracker crumbs, semi-sweet chocolate, unsalted butter, peanut butter, blanched almonds and more.
