1/2 cup butter 
2 cups shredded Cheddar cheese 
1 egg, separated 
30 bread squares 
30 shrimps, cooked and cleaned 

Cream butter and cheese. Blend in egg yolk. In a separate bowl, beat egg white until stiff peaks form. Fold beaten egg white into creamed mixture.

Arrange the bread squares on an ungreased cookie sheet. Top each bread square with one shrimp and cover with rounded teaspoonful of the cheese mixture. Bake at 350° for about 15 minutes, or until golden brown. 

These can be prepared up to 24 hours in advance; keep refrigerated until cooking time. Serve hot. Makes 30 shrimp and cheese puff appetizers.
