Seafood Empanaditas

Directions

1. 1.

   Stir salt into hot water until dissolved.

2. 2.

   Sift flour, baking powder, and sugar into a large bowl, then make a well in center and add lard and butter. Stir salted water into well with a wooden spoon, melting lard and butter, then stir flour into liquid, adding a little water if necessary, to form a soft and pliable dough. Knead dough on an unfloured surface until smooth and glossy, 3 to 5 minutes (dough will be soft and slightly sticky).

3. 3.

   Cover dough with a kitchen towel (not terry cloth).

4. 4.

   Cook clams in wine in a medium saucepan, covered, over medium-high heat until just opened wide, about 5 minutes (discard any that remain unopened). Transfer clams to a bowl with a slotted spoon, then cook mussels in same liquid, covered, stirring once or twice, until opened, 3 to 5 minutes (discard unopened ones). Add mussels to clams and strain cooking liquid through a paper-towel-lined sieve into a bowl.
