Gather all ingredients.

Beat egg in a medium bowl. Mix in 1/3 cup water.

Combine flour and salt in a large bowl. Create a well in the center of the flour mixture and slowly pour in egg and water.

Mix well. If the mixture is too dry, increase the amount of water 1 teaspoon at a time until a pliable dough has formed.

Knead dough on a lightly floured surface until elastic.

Cut dough into two separate balls. Cover dough balls with a damp cloth for a minimum of 10 minutes.

Cut each ball into four equal pieces.

Roll the pieces into 10 ½ x 10 ½-inch squares. Then cut each square into nine 3 ½ x 3 ½-inch squares for a total of 72 wonton wrappers.
