Raised Yeast Waffles

I tried this recipe tonight and LOVED it! I love waffles for dinner and these are particuarly good because they are really light and crispy. It's a totally different type of waffle then what you get from a mix.

INGREDIENTS
1 (.25 ounce) package active dry yeast (that's 2 1/2 tsp)
1 teaspoon sugar
1/2 cup warm water
2 cups warm milk
2 eggs
1/2 cup butter or margarine, melted
2 cups all-purpose flour
1 teaspoon salt
1/8 teaspoon baking soda

DIRECTIONS
In a mixing bowl, dissolve yeast and sugar in warm water; let stand for 5 minutes. Beat in the milk, eggs and butter. Combine the flour, salt and baking soda; stir into yeast mixture just until combine. Cover and let rise in a warm place until doubled, about 45 minutes.

Bake in a preheated waffle iron according to manufacturer's directions until golden brown.
