One of the most important ingredient found in this spring roll is the root vegetable, jicama (pronounced hee-kha-ma), also known as Mexican turnip. Here's a picture of a jicama (on left). As you can see, the exterior is papery brown while the inside is white and has the texture almost like a cross between a daikon and an apple. Like daikon, it tastes refreshing but just not as bitter. While the jicama can be eaten raw (like in salads), it can also be cooked them and it is an integral part of this deep-fried spring roll's filling.For the filling, I julienned jicama, carrots, Chinese chives, garlic and onions. If you are making a vegetarian version, you can also add tofu and broccoli. I made this one with the addition of chicken and broccoli because I had some leftover chicken stir fry from the day before. The best thing about these types of spring roll fillings is you can add most anything you like. You can make a seafood version with shrimp and scallops or a vegetarian version that I just mentioned earlier. Cook the filling like you would a stir fry with a little bit of soy sauce and oyster sauce. Just make sure that the final product does not contain too much gravy. Too soupy and the filling has a bad habit of leaking out from the wrapper and you'll have a hard time when deep-frying. In the following sequence of photos, I'll show you how to wrap the spring roll.
