Wrap Wan Tan dough (approx. 10 x 10 cm) in a damp tea towel and allow to defrost. Wash the sprouts and let them drip off. Clean, peel and wash the carrots. Clean and wash spring onions.
Cut everything very small. Mix with soy sauce. Brush the edges of the Wan Tan leaves with a little water in portions (must not dry out!). Put about 1 teaspoon of filling on one half of the leaves.
Overfold diagonally to form triangles, press down well. Heat oil and fry for 2-3 minutes in portions until golden brown. Drain on kitchen paper.
