This is a truly great — and mostly simple — preparation. If you’ve never tasted it before, you’re missing one of the world’s ultimate afternoon tea (or coffee) accompaniments. Gâteau Basque is really quite an unassuming little pastry. Classically it has but one filling: black cherry preserves or pastry cream. However I’ve seen versions with up to three: pastry cream plus fruit preserves plus almond cream. That seems excessive to me, since it’s the simplicity of a gâteau Basque that makes it so remarkable. I’m opening to being persuaded of course. Cash bribes are also welcome. The tip jar over there on the left is capable of receiving sums into the low five figures.
