Combine evaporated and whole milk, egg, vanilla, salt, and pepper.
Soak clams in liquid for a few mins., then dredge in combination of cake flour and cornmeal, fluffing them in the flour mix for light, but thorough coverage.
Shake off excess flour.
Heat oil to 375*F.
Immediately drop the floured clams into the hot oil, and deep-fry for 1-2 mins., until golden brown.
