Pour oil into a large deep fryer; heat to 375 degrees. Arrange 6 bread slices in a single layer on a work surface. Place 1 cheese slice on each of the 6 bread slices; top each with 2 ounces ham. Spread 1 tablespoon mustard over each of the remaining 6 bread slices; place bread, mustard side down on ham. Cut each sandwich in half diagonally.
Combine flour, cornstarch, baking powder and salt in a large shallow dish. Combine milk and eggs, stirring well with a whisk. Slowly add milk to flour mixture, stirring constantly until smooth.
Dip sandwiches in batter. Carefully lower 6 sandwich halves into oil; fry at 375 degrees for 1 1/2 minutes. Using a slotted spoon, carefully turn each sandwich half over; fry an additional 1 1/2 minutes or until golden. Repeat frying procedure with remaining 6 sandwich halves. Serve immediately.
There are two options when frying a turkey. You can take the traditional approach and use propane fryers. They should be used outdoors in accordance with the manufacturer’s safety procedures. Never use them on a wooden deck or leave them unattended. Or you can use a Master built Electric Deep Fryer that can be used indoors on kitchen counter tops, tables, inside garages and on covered patios. Be sure to keep children and pets away. But either way you choose, always remember:
- Wear oven mitts.
- Avoid use of alcohol and keep a fire extinguisher nearby, as you would with any type of cooking.
