Ham and Cheese Waffles

I am fond of eating waffles when I was a kid, now that I am old it's time to make it for the kids. :-)
Ingredients for 10-12 waffles:
250 grams flour
100 grams corn starch
100 grams sugar
5 grams baking powder
7 grams salt
600 ml fresh milk
1 tablespoon butter or margarine
1 teaspoon oil
1 egg yolk
1 egg white ( beaten until foamy)
1/2 cup diced ham
1/2 cup grated cheese


Procedure:
1. In a blender put the egg yolk, salt, sugar, baking powder, oil, butter and milk then blend for a minute, add the cornstarch and flour then blend until  no more lumps.
2. Pour the mixture in a big mixing bowl then fold in the egg white and continue folding until fully combined.
3. Set the waffle machine  at 250C and brush it with butter, when it is hot, pour each mold up to 1/2 full then put the some ham and cheese, add more batter until totally full and close the cover and wait for 2-3 minutes or until cooked.
4. Waffles are now ready to be served.
