In a large bowl, combine the ground beef and lamb.
Add the grated onion, minced garlic, paprika, cumin, black pepper, salt, and baking soda.
Gradually add the cold water while mixing, ensuring that the mixture is well combined and slightly sticky.
Cover the bowl and refrigerate for at least 1 hour to allow the flavors to meld.
Once chilled, divide the mixture into small portions and shape each portion into small, finger-sized sausages (about 4 inches long).
Preheat your grill or grill pan to medium-high heat.
Lightly oil the grill grates to prevent sticking.
Place the kebapi on the grill and cook for 6-8 minutes, turning occasionally, until they are well browned and cooked through. The internal temperature should reach 160°F (71°C).
Enjoy your meal!
