1/2 c. sugar
2 Tbsp. cornstarch or flour
1/4 tsp. salt

In a large bowl, thoroughly mix 1 1/3 cups flour, 1 teaspoon sugar and dry yeast.
Combine milk, water and margarine in a saucepan.
Heat over low heat until liquids are warm (margarine need not be melted).
Gradually add to dry ingredients and beat 2 minutes at medium speed with electric mixer, scraping bowl occasionally.
Add egg yolks and 1/2 cup flour or enough flour to make a thick batter.
Beat at high speed 2 minutes, scraping bowl occasionally.
