Make the chilli oil first. Put the Sichuan peppercorn and chili flake into a bowl. Heat up the chili oil on low heat. The oil should be heated up to the point where you can see tiny bubbles when you put in fork or a knife.
Pour the oil gently into the bowl with the chili flake. It will bubble, wait until bubbling subsides.
Add in the rest of the ingredients into the oil and set aside.
Boil water for noodles
Cut the carrots, cucumbers and cilantro and set aside
strain the stock of your choice and set aside
Once the water boils, put in your noodles. Turn it to medium, boil for about 6 min.
Drain your noodles and immediately rinse with cold water. This stops the cooking process and makes the noodles chewier. Place your noodles into the individual bowls.
Assemble all your prepared ingredients and top up with the dressing. Add some vinegar to help balance the chili oil dressing.
Notes
I like adding in vinegar because it helps to balance the chili oil and also add some freshness to the dish.
