The best part happens right at the end. Chili powder lands on the hot potatoes, cumin follows, then a handful of white sesame scatters across the wok. A few fast tosses wake everything up. You can almost smell that moment through the screen.
These potato cubes are cooked slowly at first, until the centers soften and a few sides turn golden. Only then do the sausage and dry seasonings go in. It is a small change in heat, but it keeps the cumin fragrant instead of bitter.
Ingredients
- 2 medium potatoes, peeled and cut into small, even cubes
- 1–2 small Chinese-style ham sausages, cut into thick rounds
- 2 tablespoons neutral cooking oil, plus a little more if needed
- 1/2 teaspoon salt, or to taste
- 1/2–1 teaspoon chili powder, adjusted to taste
- 1 1/2 teaspoons ground cumin
- 1 tablespoon white sesame seeds
- 2 scallions, finely chopped

How to Make Chinese Cumin Potato Cubes
Cut the potatoes and sausage
Keep the potato cubes fairly small and close in size. Slice the sausage into thick rounds or pieces about the same size. Nothing needs to be ruler-perfect; the goal is simply to help everything cook at roughly the same pace.
Give the potatoes time
Heat the oil in a wok or wide skillet, then add the potato cubes. Spread them out and cook over medium-low heat, turning them every so often. Wait for a few flat sides to turn lightly golden and check that the centers are tender.
Do not rush this with high heat. Potatoes can brown outside while staying firm in the middle. If the wok starts looking dry, add a little oil instead of turning the burner all the way up.

Add the sausage and salt
Once the potatoes are almost done, add the sausage. Toss it through the wok until the cut sides are hot and lightly colored, then season with salt.
Wake up the chili, cumin, and sesame
Now add the chili powder, ground cumin, and white sesame. Turn the heat up and keep everything moving. This part only takes a short burst. The seasonings should coat the potatoes and smell warm and toasty, but they should not sit long enough to scorch.

For a lightly numbing variation, replace part of the plain chili powder with RuralMala Erjingtiao chili flakes with Sichuan pepper powder. Add it with the cumin and sesame so the oil can release the aroma without covering the cumin completely.

Finish with scallions
Turn off the heat, add the chopped scallions, and toss once more. Eat the potatoes while the edges are hot and the cumin aroma is still hanging over the wok.
A Few Things That Make a Difference
Ground cumin and chili powder need hot oil, but they do not need a long cooking time. Add them after the potatoes are tender. If the chili turns dark brown or the cumin starts smelling bitter, the heat is too aggressive or the seasonings have stayed in one spot too long.
For a mild batch, leave out the chili and keep the cumin and sesame. For more heat, add extra chili in small steps. The cumin should still be easy to recognize.
Chinese-style ham sausage gives the dish a salty, springy bite. A mild hot dog or fully cooked sausage works when that is what you can find. Skip anything heavily smoked; it tends to take over the pan.
The sausage is optional. Potatoes, cumin, chili, sesame, and scallions make a good meat-free version on their own. Just taste before serving and adjust the salt.
