Origins: the Daquiri

If you're an American mine employee stuck working in Cuba, what do you do? In the case of intrepid engineer Jennings Cox, you start creatively mixing drinks. The mixture of rum, lime, and sugar supposedly sprang to life in 1905 when Cox and some of his fellow Americans were hanging out in a bar in Santiago, Cuba. By mixing together these handy ingredients, the Americans found a tasty tipple, and it eventually worked its way back to the states. (Mental Floss)
