Stracciatella
Just about every gelateria in Italy features a bin of stracciatella, vanilla ice cream with chocolate “chips.” It results from a technique that clever Italians devised for pouring warm, melted chocolate into cold ice cream. The flow of chocolate immediately hardens into streaks, which get shredded (stracciato) into “chips” as the ice cream is stirred. The trick to stracciatella is to pour it into your ice cream maker in a very thin stream during the last moment of churning. If your aim isn’t very good, or your ice cream machine has a small opening, transfer the melted chocolate into a measuring cup with a pouring spout. (If you’re using a microwave to melt the chocolate, simply melt the chocolate in the measuring cup.) The trick is to pour it not on the turning dasher (mixing blade) but into the ice cream itself. You can also drizzle it over the ice cream as you layer it into the storage container, stirring it very slightly while you’re pouring.
