Prep: 40 min | Cook: 43 min | Total: 1 hr 38 min

Cost: $1.36 total, $0.34 per serving

Ingredients

  • 250 g Sweet potatoes (Peeled and cut into large pieces)
  • 125 g Tapioca starch (Provides elasticity and a fluffy texture)
  • 50 g White sugar (Adds a light sweetness)
  • 0.5 c. à café Salt (Half a teaspoon)
  • 200 ml Sunflower oil (For frying, depth about 2 cm)

Instructions

  1. Peel and cut the sweet potatoes

    Peel 250 g of sweet potatoes then cut them into uniformly sized large pieces.

    Time: PT5M

  2. Steam cooking

    Place the pieces directly in the steamer basket over a pot of simmering water. Cover and cook for 15 minutes.

    Time: PT15M

    Temperature: 100°C

  3. Evaporate excess water

    Remove the basket lid and let the potatoes rest for an additional 15 minutes to evaporate residual moisture.

    Time: PT15M

  4. Mash the potatoes

    Transfer the cooked potatoes to a large bowl and mash them with a fork or spatula until you obtain a smooth purée.

    Time: PT5M

  5. Incorporate dry ingredients

    Add 125 g of tapioca starch, 50 g of sugar and 0.5 c. à café of salt. Mix first with a spatula, then knead by hand for a few minutes until you get a homogeneous dough.

    Time: PT10M

  6. Dough resting

    Cover the bowl with plastic wrap or a damp cloth and let rest for 10 minutes. The starch absorbs moisture and the dough firms up slightly.

    Time: PT10M

  7. Shape the balls

    Using a half‑teaspoon, scoop dough and roll it between your hands to form small balls the size of a cherry (about 12 mm in diameter). You should obtain about 50 balls.

    Time: PT5M

  8. Heat the oil

    Pour about 2 cm of sunflower oil into the large pan and heat over medium‑low heat until it reaches 120 °C. Test with a small ball: small bubbles should form around it.

    Time: PT5M

    Temperature: 120°C

  9. First fry (setup)

    Place about fifteen balls in the hot oil. Stir gently for 1 minute to prevent them from sticking.

    Time: PT1M

    Temperature: 120°C

  10. Stabilize the temperature

    Lower the heat slightly so the temperature rises slowly and stabilizes between 150 °C and 160 °C.

    Time: PT1M

    Temperature: 150-160°C

  11. Pressing and puffing

    After 1 minute, use a slotted spoon to gently press each ball while turning them. Continue pressing for an additional 1 minute.

    Time: PT1M

    Temperature: 150-160°C

  12. Final cooking

    Cook for an additional 3 to 4 minutes until the balls are golden and have doubled in volume.

    Time: PT4M

    Temperature: 150-160°C

  13. Drain and cool

    Remove the balls with the slotted spoon and place them on a rack to drain excess oil.

    Time: PT2M
