Lamb Dumplings With Cucumber Vinegar Dipping Sauce

Heat a few tablespoons of olive oil in a skillet as cook onion, garlic, and potato until nicely browned. Add 1 teaspoon cinnamon and 1/2 teaspoon cumin and stir to combine.
In a medium bowl, add onion, garlic and potato to the ground lamb. Add remaining 1/2 teaspoon cumin, 1/2 teaspoon cinnamon, 1/2 teaspoon coriander, 1/2 teaspoon each salt and pepper, and fresh mint. Mix with your hands until well combined.
In the center of each potsticker wrapper, place a teaspoon or less of filling. Draw the wrapper up around the filling and twist at the top to seal. Moisten fingers with water if necessary.
Heat water in a saucepan with a steamer basket. Moisten hands with olive oil and place dumplings in the basket, coating with olive oil from your hands as you do so. Be careful not to crowd the basket as the dumplings will stick together-steam in batches if necessary. Cover and steam for at least 5 minutes.
In a heavy skillet, heat a 1/2 inch of oil until it begins to smoke. Remove dumplings from steamer basket and pan-fry until crispy and brown on the bottoms.
Using a citrus zester or fine grater, grate peeled cucumber over a small bowl. Cucumber juice, along with a little pulp, is the desired result. Add salt and rice vinegar and stir to combine.
Remove dumplings from skillet and drain on a paper towel. Serve with the cucumber dipping sauce while still hot.
