Lettuce is the primary vegetable for the rice rolls, just like salad. The large piece of leaf holds other vegetables and herbs on it to minimize the smaller pieces from falling off to the edge of the rice paper that makes wrapping difficult.
Other universal inclusion ae carrot and cucumber. The crunchiness provides a big contrast with the sticky rice paper and squidgy vermicelli, rendering a satisfying mouthfeel for every bite.
You can cut them in julienne or thin slices. I prefer to cut it into matchsticks. The Japanese Mandolin makes this an easy task because I can slice the carrots and cucumber to any thickness. Stack up the slices and use a sharp knife to cut them in into fine julienne.
Another common add-on is bean sprouts. I did not include it in this recipe since there are filled with carrots and cucumbers, which is already provide sufficient crunchiness to the rice paper rolls.
The herbs
Various herbs provide the aroma lingering on your palate from your first bite. These are the typical Vietnamese herbs–basil, coriander, and mint.
Use any one of them or in combination. These are the common herbs used in Vietnamese cuisine. If you eat pho, you will sure to have plenty of basil, mint, and coriander too. You can omit either one is if you are not a fan of any of these.
Besides, scallion is a welcome addition. You can let the green section of the scallion protrude from both sides of the rice rolls as garnish.
The rice vermicelli
The inclusion of rice vermicelli qualifies the rice rolls as a completes meal- carbohydrate, proteins, fibers and some fats from the peanut butter sauce.
You do not need to cook the rice vermicelli. All you need is to soak it in hot water (do not boil) for about five minutes. The rice vermicelli will start to turn soft, and al dented. The actual duration depends on the temperature of the water and the diameter of the rice vermicelli.
Test the doneness at a one-minute interval after the third minute. Once it is al dente, drain and place it in cold water to stop cooking. Drain again, and it is ready to use. The texture should be yielding but still chewy.
The rice papers (wrappers)
The rice paper is brittle, and become sticky when it turns wet. Therefore, it is essential to keep it dry all the time.
Before you start to wrap the rice paper rolls, get ready a shallow plate of water to wet the rice papers.
There are various suggestions on how to soften the rice papers. This range from soaking with hot water to place it on kitchen towels to remove the excess water. I find that the simplest way is to use cold water, as hot water tends to soften it too fast. It may become too soft and sticky if you are slow in arranging all the ingredients on the rice papers before wrapping it.
Wrapping the rice paper rolls
There is no hard and fast rule, but I would mention how I do it for your reference.
- Mise en place. Get all the ingredients ready because you must start to wrap within a minutes after you wet the rice paper, or it will become too sticky and unmanageable.
- Submerge the rice paper fully into cold water for five seconds just before wrapping.
- Remove it and place on a clean chopping board or tabletop. Dab the rice paper with a dry kitchen towel to remove the excessive water.
Turn over the rice paper and dab dry the other side. Place it back on the dry chopping board.
- Choose a piece of lettuce with the length about 2/3 of the diameter of the rice paper. Place the carrot, cucumber and rice vermicelli and herbs on the lettuce. Position the rice paper, slightly off-centered towards you, and leave about one inch clear from the side.
