In a small bowl, whisk together all ingredients except sliced scallions. Set aside.
Add enough oil to a large deep pot or dutch oven to come up the sides at least 3 inches. Attach a high heat thermometer to the side and heat oil to 350℉. Alternatively, you can use a deep fryer set to 350℉.
In a medium bowl whisk together water, flour, white wine, egg, cornstarch, baking soda and salt until smooth. Set aside while oil is heating and asparagus is prepped.
Trim woody ends from asparagus (about 2"). If some stalks are quite a bit thicker than others, thin by lightly peeling with a vegetable peeler to create more uniform stalks.
Once the oil is hot, dip individual asparagus spears into batter to evenly coat and tap off excess batter. Add to hot oil one at a time, cooking 6-8 per batch and cook for about 2 minutes per side depending on size. Remove with a slotted scoop to a paper towel lined tray and repeat with remaining asparagus.
Divided soy dipping sauce into small serving bowls and serve asparagus along side. Garnish with scallions and serve immediately.
Stir together all ingredients and chill until ready to use.
Add all ingredients to a large bowl and gently mix with your hands until well combined but not overworked. Cover and chill for up to one day in advance. Shape approximately 2 1/2 ounces of meat mixture into a 3" long log, making 13-15 in total. Thread onto skewers and chill until ready to grill.
Preheat heat grill to medium and grill lamb skewers for approximately 12 minutes turning to brown all sides. Meat should no longer be pink and the internal temperature should reach a minimum 160℉. Split pitas and fill with 2 koftas. Top with Minted Yogurt Sauce and desired toppings such as lettuce, sprouts, and onions.
Recipe makes approximately 35 ounces of mixture and can be made into burger patties as well. I used metal skewers, however if using wooden skewers be sure to soak in water according to directions prior to use.
