Ingredients
  

For noodles & veggies:
  • 1 cup soba noodles
  • 1 small carrot julienned
  • ½ red bell pepper sliced
  • ½ cup red cabbage thinly sliced
  • 2 tbsp spring onions chopped
  • 1 tbsp cilantro chopped
  • ½ cup edamame peeled
For Peanut Sauce:
  • 2 tbsp smooth peanut butter
  • 1 tbsp soy sauce
  • 1 tbsp lemon juice
  • 1 tsp ginger-garlic paste
  • 1 tsp brown sugar
  • ½ tsp chilli flakes
For garnish:
  • 1 tsp toasted sesame seeds
  • 1 tbsp crushed peanuts
  • Extra spring onions

Method
 

  1. Cook the soba noodles according to package instructions. Drain and rinse with cold water to stop the cooking process, then set aside to cool completely.
  2. In the meantime, prepare all the vegetables by slicing the carrot, red bell pepper, and red cabbage. Chop the spring onions and cilantro, and peel the edamame. Set everything aside.
  3. In a small bowl, whisk together the peanut butter, soy sauce, lemon juice, ginger-garlic paste, brown sugar, and chilli flakes until smooth and creamy.
  4. To assemble, add the peanut sauce to the bottom of an airtight container or glass jar. Layer the soba noodles directly over the sauce so they can absorb the flavors over time.
  5. Add the prepared vegetables on top of the noodles, followed by the edamame. Finish with a sprinkle of toasted sesame seeds, crushed peanuts, and fresh spring onions.
  6. Seal the jar and refrigerate until ready to serve. Mix everything together before eating for the best flavor.
    7. Layer strategically for freshness: Always keep the peanut butter at the bottom and noodles just above it. This prevents sogginess and keeps the veggies crisp until mixing.
    Slice, don’t dice: Thinly slicing vegetables (especially bell peppers and carrots) ensures better texture, easier mixing, and a more premium, visually clean jar.
    Use cooled noodles only: Adding warm noodles will create condensation, making the jar watery and reducing shelf life.
    Don’t overpack: Slight gaps between layers help maintain structure and make shaking/mixing easier when ready to eat.
    Seal tightly for storage: With a proper lid, this jar can last up to 2-3 days in the fridge without losing texture.
    Mix before eating, not before storing: Shake the jar or transfer to a bowl just before eating to evenly coat everything in the peanut layer.
    Add crunch at the end: If you want extra texture (like peanuts or crispy toppings), add them just before eating-not during layering.
    Balance the peanut layer: If your peanut butter is too thick, loosen it slightly with lime juice or water so it mixes better later.
