  • 6 eggs
  • 200 g sweet potato noodles
  • 3 tbsp soy sauce
  • 1 tbsp sesame oil
  • 1 carrot
  • 1 cup spinach
  • 1 tbsp sugar
  • 2 tbsp cooking oil
  • Salt and black pepper, to taste

Method

  1. Step 1. Cut everything into bite-size pieces so it cooks evenly; mix sesame oil and carrot into a quick sauce.

    Heat
    Off, no heat yet
    Look for
    Pieces are roughly the same size, so they all finish cooking together.
    Why it matters
    Even pieces cook at the same speed. Prepping everything first (mise en place) stops you scrambling once the pan is hot.
    Avoid
    Cutting pieces of mixed sizes: small ones burn while big ones stay raw.

  2. Step 2. Heat a wok until almost smoking, then add a spoonful of oil.

    Heat
    Medium to high
    Look for
    The oil shimmers and flows like water; a drop of water sizzles instantly.
    Why it matters
    Food added to a properly hot pan sears and browns instead of steaming and sticking.
    Avoid
    Adding food to a cold pan: it sticks, turns grey and soaks up oil.

  3. Step 3. Sear the egg in batches for about 3 minutes until browned; remove to a plate.

    Heat
    Medium to high, stir or flip now and then
    Look for
    Golden-brown edges, a steady sizzle and a toasty smell.
    Why it matters
    Browning (the Maillard reaction) creates deep savoury flavour that boiling cannot.
    Avoid
    Overcrowding the pan: the temperature drops and food steams. Cook in batches.

  4. Step 4. Stir-fry the sweet potato noodles and soy sauce for 1 minute until fragrant.

    Heat
    Medium to high, stir or flip now and then
    Look for
    Golden-brown edges, a steady sizzle and a toasty smell.
    Why it matters
    Browning (the Maillard reaction) creates deep savoury flavour that boiling cannot.
    Avoid
    Overcrowding the pan: the temperature drops and food steams. Cook in batches.

  5. Step 5. Return the egg, pour in the sauce and toss over high heat for 2 minutes.

    Heat
    Keep the heat steady
    Look for
    The new ingredient is coated and the mixture returns to a gentle bubble.
    Why it matters
    Adding things in order lets each ingredient cook for just the right time.
    Avoid
    Dumping everything in at once: delicate items turn mushy before tougher ones are done.

  6. Step 6. Taste, adjust the seasoning and serve immediately with sugar.

    Heat
    Off, no heat
    Look for
    Everything is evenly coated or just combined, with no dry pockets.
    Why it matters
    Mixing spreads salt, fat and flavour through the food so every bite tastes the same.
    Avoid
    Overmixing batters and doughs makes them tough; stop once just combined.
