I don’t know what it is about Sambuca, the colorless anise and elderflower-flavored liqueur. The ancients believed anise to be an aphrodisiac, but I don’t set much store by such things. For me, a sip of Sambuca is something of an amorous madeleine, causing scenes of love both chaste and profane (profane but profound) to unfold in memory. Of course, to have such a Proustian moment, one needs the original experience. Without risking further indiscretion, I’ll say only that I’ve made these cookies for my family at Christmas and for one or two very small, very successful dinner parties.
