— A.C.A. Tres leches cake was introduced to San Antonio largely through the efforts of Blanca Aldaco. Since then, you can find it at numerous places across town, and many of the versions are fine. But Aldaco still serves the best to be had. The name tres leches refers to the three milks that are used to keep the cake moist. The lineup can vary, but it is usually sweetened condensed milk, evaporated milk and heavy cream. What Aldaco does with this cake at her restaurant in Stone Oak, 20079 Stone Oak Parkway, is always rich and delicious. She also varies the flavors she offers, depending on the season. The current lineup includes chocolate and Kahlúa in addition to the regular style Call 210-494-0561.
