Budín de CaféCoffee-flavored flans and puddings are popular in Mexico. This one is flavored with coffee essence made from instant coffee. (If a stronger coffee flavor is preferred, instant espresso may be used.) Instant coffee is widely available in Mexico. Before instant coffee was available, a very strong brewed coffee would flavor the budín. Mexico produces a great deal of coffee that's grown in the highlands of southern Mexico. The pudding should be served the day it's made.
