In a medium bowl, whisk together milk, flour,
eggs, and salt until smooth. Alternatively,
place everything in a blender and blend until
smooth. Set aside for 20-30 minutes while oven
is preheating. Preheat oven to 425 degrees F.
Place butter in a 9x13 glass baking dish. Heat
in oven for 5-10 minutes, until butter is
completely melted and foaming. Remove pan from
oven and tilt to cover the bottom entirely with
the butter. Remove from oven and pour batter
into the pan. Quickly top with the diced ham,
shredded cheese and herbs. Bake for about 20-25
minutes, or until it is puffed up and the
cheese is golden brown and bubbly. Cool
slightly before serving. Serve with fruit or a
small green salad. Makes enough for 4-6 people.
