Ingredients

  • 2 lb New Potatoes (small yellow or red new potatoes, washed)
  • 1/4 cup Kosher Salt (for heavily salted boiling water (≈4% salinity))
  • 2 tsp Sichuan Peppercorns (toasted, husks only)
  • 2 tsp Cumin Seeds (toasted; half will be ground, half left whole for texture)
  • 1 piece Star Anise (whole pod, toasted)
  • 1 tsp Fennel Seeds (toasted)
  • 1 tsp White Peppercorns (toasted)
  • 3 pieces Dried Small Hot Chilies (Urging chowo or Thai dried chilies, roughly 1 tsp when broken)
  • 1 tsp Granulated Sugar
  • 1 tsp Chicken Bouillon Powder (adds umami; can substitute with MSG + salt)
  • 2 tbsp Roasted Sesame Seeds (adds nutty crunch)
  • 3 tbsp Peanut Oil (high smoke‑point oil; can use rapeseed or vegetable oil)
  • 3 pieces Garlic Cloves (smashed)
  • 2 stalks Scallions (cut into ½‑inch pieces)

Instructions

  1. Boil Potatoes

    Place the washed new potatoes in a large pot, cover with cold water, add a generous amount of kosher salt (water should taste as salty as seawater), bring to a boil, and cook for about 10 minutes until a fork slides in with little resistance but the potatoes hold their shape.

    Time: PT10M

    Temperature: 100°C

  2. Dry Potatoes

    Drain the potatoes in a colander and spread them on a sheet tray. Let them steam‑dry for 5 minutes so the surface becomes dry and the salty coating sets.

    Time: PT5M

  3. Toast Whole Spices

    In a dry small skillet over medium‑high heat, add the Sichuan peppercorns, cumin seeds, star anise, fennel seeds, and white peppercorns. Stir constantly and toast until fragrant, about 2 minutes.

    Time: PT2M

    Temperature: medium‑high

  4. Grind Toasted Spices

    Transfer the toasted spices to a mortar and pestle and grind coarsely, leaving some texture.

    Time: PT1M

  5. Stir‑Fry Cumin and Chilies

    In the same skillet, add 1 tsp whole cumin seeds and the dried chilies. Stir‑fry for about 30 seconds until the cumin pops and the chilies become aromatic, being careful not to let them burn.

    Time: PT30S

    Temperature: medium‑high

  6. Assemble Spice Mix

    In a bowl combine the ground toasted spices, the half‑ground cumin seeds from step 5, 1 tsp sugar, 1 tsp salt, 1 tsp chicken bouillon powder, and 2 tbsp roasted sesame seeds. Mix thoroughly.

    Time: PT2M

  7. Heat Oil

    Heat 3 tbsp peanut (or rapeseed) oil in a wok over high heat until it just begins to smoke, about 2 minutes.

    Time: PT2M

    Temperature: 190°C

  8. Stir‑Fry Potatoes

    Carefully add the dried potatoes to the hot oil (use a spatula to lower them to avoid splashing). Stir‑fry for 5 minutes, turning occasionally, until the exterior is golden‑brown and crisp.

    Time: PT5M

    Temperature: 190°C

  9. Add Garlic and Scallions

    Push the potatoes to the side, add a splash more oil if the pan looks dry, then add the smashed garlic cloves and sliced scallions. Stir‑fry for 1 minute until fragrant but not browned.

    Time: PT1M

    Temperature: 190°C

  10. Season and Toss

    Sprinkle the entire spice mix over the potatoes, toss quickly to coat evenly, and cook another minute so the flavors meld.

    Time: PT1M

    Temperature: 190°C

  11. Finish and Clean

    Transfer the potatoes to a serving dish. While the wok is still hot, give it a quick scrub with a bamboo brush, then set it aside to dry.

    Time: PT5M

  • For extra crunch, add a handful of fried shallots just before serving.

Troubleshooting

Potatoes are soggy instead of crisp.

Make sure the potatoes are completely dry before adding to the oil and that the oil is hot enough. Fry in batches if necessary.

Spice mix tastes too salty.

Reduce the added salt or use low‑sodium chicken bouillon; add a pinch of extra sugar to balance.

Spices become bitter.

Toast spices only until fragrant (about 2 minutes); remove from heat immediately if they start to darken.

Oil splatters dangerously.

Dry the potatoes thoroughly, lower them into the oil with a spatula, and consider using a splatter guard.

Storage

Refrigerator: Store in an airtight container for up to 2 days. Re‑heat in a hot skillet to regain crispness.

Freezer: Not recommended; potatoes become mushy after freezing.

Room temperature: Can sit at room temperature for up to 1 hour, but texture will soften.

Make-Ahead Tips

  • Prepare the spice mix up to a week in advance and store in a sealed jar.
  • Boiled potatoes can be cooked a day ahead; keep them dry on a tray in the fridge.
