Melt shortening/lard/butter on medium heat. Combine with flour, mixing well until a paste is formed. Add milk and season with salt and pepper. Bring to a boil, stirring, until mixture thickens.

Remove from heat, mix in crabsticks and chill for at least one hour. Shape into croquettes.

Heat oil to 175°C. Dredge the croquettes in flour, egg, and panko, coating fully. Fry until golden brown, turning occasionally, about 3 to 4 minutes. Drain excess oil on paper towels.
