Step-by-Step Instructions
Step 1. Prepare the Sweet Potatoes and Batter
- Peel and wash the sweet potatoes. Cut them into small, bite-sized pieces.
- Soak the cut potatoes in a basin of water mixed with lemon and salt to prevent sticking and remove resin. This helps keep them from becoming sticky and cleans them before mixing with the flour.
- In a bag, puree the 150g of crispy fried flour, 20g fried flour, 20g sugar, a little salt, and half a teaspoon of turmeric powder. Add an egg. Mix thoroughly.
- Add the coconut milk to the flour mixture and mix well until smooth and the sugar and salt are fully dissolved. Let the batter rest for 15 minutes.




Step 2. Coat and Rest
- Drain the soaked sweet potatoes well. Add them to the batter and mix gently until evenly coated.

Step 3. Fry the Sweet Potatoes
- Heat oil in a frying pan. Fry the sweet potato pieces until the flour is firm and golden brown. Use chopsticks to separate the pieces as they fry.

Step 4. Drain and Serve
- Remove the fried sweet potatoes and place them on a paper towel to absorb excess oil.
