Hambagu in Japan is typically made from both ground beef and ground pork, and the common ratio is 7:3. Japanese supermarkets sell a convenient package of both ground beef and ground pork so that we don't have to buy the meat separately. We use this Aibiki Niku for Korokke, Spaghetti Meat Sauce, and Hambagu recipes.

Swapping the traditional 7:3 beef-to-pork blend for 100 percent lean beef significantly alters the texture, often producing a dry patty that lacks the moisture supplied by pork fat. Achieving a proper hambagu relies almost entirely on physical manipulation rather than seasoning alone. Thoroughly chilling the formed patties for at least 30 minutes allows the proteins to bind with the panade, creating a cohesive structure that holds together over direct heat.
Scaling this formulation for larger crowds requires mixing the meat in separate batches rather than doubling everything in one bowl, which prevents uneven distribution of the panko and egg. Maintaining adequate spacing in the pan prevents the patties from steaming instead of searing properly.
