Behind a high white fence in a leafy little corner of East Dallas is the immaculate freezer plant where the city's best popsicles are made. Sold only from handcarts at a buck apiece by guys who rarely speak English, La Princesa's popsicles are made from fresh fruit and natural flavors only. In fact, if you drop in on the plant someday, you'll see big containers of watermelon, lemons, bananas and other produce trucked in the door to be turned into arctic-cold popsicles. Manufactured according to the best sanitary standards, La Princesa's popsicles stay rock-hard on dry ice in those handcarts. In fact, you want to be careful to give your popsicle a few minutes to warm up before you stick your tongue on it, or you'll wind up with a bad case of Minnesota-tongue, and what a terrible irony that would be in Texas.
