Masa tamales filled with chicken in a rich pumpkin seed pipián sauce, steamed in corn husks. These protein-packed family celebration tamales highlight a treasured pre-Hispanic flavor.
Soak dried corn husks in hot water for 30 minutes until pliable, then drain and set aside.
Toast pumpkin seeds in a dry skillet over medium heat for 4–5 minutes, stirring frequently until fragrant and beginning to pop.
In a blender, combine toasted pumpkin seeds, poblano, onion, garlic, cilantro, cumin, 1/2 tsp salt, and 1 cup chicken broth. Blend until smooth to make the pipián sauce.
Heat 2 tbsp vegetable oil in a skillet over medium heat. Pour in blended pipián sauce; simmer 8–10 minutes, stirring occasionally, until thickened. Add shredded chicken and 1/4 cup broth; simmer 3 more minutes, then remove from heat.
In a bowl, mix masa harina with remaining broth, oil, and 1/2 tsp salt to form a soft but cohesive dough. If too dry, add water 1 tbsp at a time.
Spread 2–3 tbsp masa evenly in the center of each corn husk. Place about 2 tbsp chicken pipián filling in the center, fold sides of husk to enclose, then fold up the bottom.
Arrange tamales upright in a steamer basket over simmering water. Cover with extra husks and steam, lid on, for 60–75 minutes, adding hot water as needed to avoid boiling dry.
Let tamales rest 10 minutes before serving; the masa will finish setting as they cool slightly.
