Vegetable Curry Samosas

Step 1
Heat oil in a large frying pan over medium heat. Add onion, curry powder, mustard seeds, and cumin seeds; cook for 3 minutes. Add broth and potatoes; cook until tender, 3 to 5 minutes. Add carrot and peas, cook 2 minutes more. Remove from heat and allow filling to cool.

Step 2
Preheat the oven to 400 degrees F (200 degrees C). Lightly grease a baking sheet.

Step 3
Roll puff pastry out on a work surface and cut into 16 thin rounds. Place 2 to 3 tablespoons of filling on each round. Cover edges of pastry with beaten egg and press edges together using a fork to close. Place samosas on the prepared baking sheet.

Step 4
Bake in the preheated oven until pastry is puffed and golden brown, 12 to 15 minutes.

Step 5
While samosas are baking, combine mayonnaise, sour cream, sugar, lemon juice, horseradish, curry powder, salt, and pepper in a bowl. Cover and refrigerate sauce until needed. Serve with samosas.
