Preheat a grill.
Combine the flour, corn flour, salt, and white pepper. Dip clams in evaporated milk then dredge in the seasoned flour mixture. Fill a deep pot halfway full with oil and heat to 350 degrees F.
Fry the clams in the vegetable oil for approximately 1 to 2 minutes (depending on size), until golden brown. Lightly butter a split-top hot dog roll and grill on both sides. Place clams on roll and enjoy.
