Detailed Directions and Instructions
Pickle the Vegetables
In a bowl, combine 1 1/2 cups of boiling water, 4 tsp of cooking salt, and 1/2 cup of white sugar. Stir until both the salt and sugar are dissolved. Then, add 3/4 cup of rice wine vinegar to the mixture. Submerge 2 medium carrots (cut into 2 mm batons) and 1/2 large white radish (daikon, cut similarly) in the pickling liquid. Allow them to sit for 2 hours. Afterward, drain the vegetables and set them aside for the recipe or store in the fridge submerged in the liquid.
Prepare the Peanut Sauce
In a bowl, mix together 2 tbsp of natural peanut butter, 2 tbsp of hoisin, 1 to 2 tbsp of lime juice (start with 1 tbsp), 1/3 cup of low fat coconut milk, 1 finely grated large garlic clove, 1 tsp+ of sambal oelak (chilli sauce, optional), 1 tsp of dark soy, 1 tsp of white sugar, and 1/2 tsp of cooking salt. Set aside for the flavors to meld while preparing the rest.
Prepare the Prawns
Cut 300g of cooked prawns in half horizontally and remove the vein.
Prepare the Noodles
Soak 75g of dried vermicelli noodles in boiling water according to package directions. Once soaked, rinse the noodles under cold water to prevent stickiness, then drain thoroughly.
Lay Out the Ingredients
Arrange everything on a large platter or in small bowls. Pile the vegetables, prawns, noodles, herbs, and any other ingredients for everyone to help themselves.
Assemble the Lettuce Cups
To assemble, take a large or small lettuce leaf and layer the ingredients in the following order: noodles first, then the vegetables (like pickled carrots and bean sprouts), followed by prawns. Stuff herbs such as mint and coriander down the side, drizzle with peanut sauce, and sprinkle with chopped peanuts and finely sliced chilli if desired. Bundle the lettuce leaf and take a bite!
Notes
Note on Prawns
You can cook your own prawns by tossing 300g of raw peeled prawns with a little salt and pepper. Preheat oil in a non-stick pan over high heat and cook each side for approximately 1.5 to 2 minutes, depending on the size, before removing them from the heat.
Note on Peanut Butter
Natural peanut butter contains just peanuts without added sugar or salt, providing a more intense flavor and a runnier texture ideal for sauces. If using regular peanut butter spread, the sauce will be thicker and may have a slightly different flavor.
Note on Coconut Milk
Using low fat coconut milk creates a thinner sauce. If you only have full fat coconut milk, use 1/4 cup and top up with water to achieve the desired consistency.
Note on Soy Sauce
Dark soy sauce provides a richer flavor and darker color for the sauce. You can substitute it with light or all-purpose soy sauce if needed.
Leftover Storage
The peanut sauce can be stored in the refrigerator for up to 4 days or frozen for 3 months. The pickled vegetables last for weeks in the fridge.

Cook techniques
Quick Pickling
To quick pickle vegetables, dissolve sugar and salt in boiling water, then mix in rice wine vinegar. Submerge the prepared vegetables and let them sit for at least 2 hours to achieve desired tartness.
Preparation of Peanut Sauce
Combine natural peanut butter, hoisin sauce, lime juice (or rice vinegar), low-fat coconut milk, grated garlic, sambal oelek (if using), dark soy sauce, sugar, and salt in a mixing bowl. Mix thoroughly and allow the flavors to meld.
Preparing Prawns (Shrimp)
For using cooked prawns, simply cut them in half horizontally and remove any veins. If starting with raw prawns, toss them with salt and pepper, preheat oil in a non-stick pan, and cook for 1.5 to 2 minutes on each side.
Noodle Preparation
Soak the dried vermicelli noodles in boiling water according to package directions. Rinse under cold water to prevent stickiness, then drain well.
Assembling Lettuce Cups
For assembly, place a lettuce leaf on a plate, followed by a portion of soaked noodles, then add the pickled vegetables, prawns, and fresh herbs. Drizzle with peanut sauce and sprinkle with chopped peanuts and chili before folding and enjoying.
