- To make momo dough, combine flour, oil, water, and sea salt in a medium mixing bowl. Use hands to form into dough, adding an extra couple teaspoons of warm water as needed. Knead dough for 10 minutes. Place dough into mixing bowl and cover with a clean kitchen towel. Set in a warm spot for 20 minutes.
- In the meantime, heat 1 teaspoon of sesame oil over medium heat in a medium skillet. Add cabbage, carrots, onion and jalapeño. Sauté for 5 minutes. Stir in garlic, ginger and 1 tablespoon soy sauce and continue to cook for 5 minutes longer or until cabbage is tender. Remove from heat.
- Knead dough for 2 minutes longer. Tear off balls of dough (about 2 tablespoons each) and roll out into a thin 3-4-inch circle. Fill with 1 tablespoon of vegetable filling and fold together to sides creating a triangle. Pinch the ends and fold the top to close the momo. Pinch all ends to seal. Repeat with remaining dough.
- Heat a thin layer of water in a steam pot over medium-high heat. Once water is boiling, add 3-4 momos to steam rack and cover with lid. Steam for 10 minutes. Remove momos from pot and transfer to a bowl with a lid to keep them warm. Repeat with remaining momos.
- While momos are steaming, stir together peanut butter, remaining sesame oil, remaining soy sauce, lime juice, and honey until smooth. Serve momos hot alongside peanut sauce for dipping.
