I couldn't bear to throw out the one egg white I had left over from yesterday's cookie baking(jam pockets). so I tried again.
Amaretti recipe for 1 egg white -
Preheat oven to 300F
5/8 cup almonds ground and sifted into bowl
¾ tsp. Cornstarch
¼ cup confectioners sugar, sifted into bowl
Combine all three in a bowl and mix well.
1 egg white
pinch cream of tartar
3 T. granulated sugar
In a separate bowl, beat 1 egg white and a pinch of cream of tartar until foamy. Gradually add 3 T. granulated sugar one T. at a time beating well after each addition. Continue to be the egg white until stiff peaks form.
1/8 tsp. Almond extract
Fold in the almond mixture and almond extract into the egg white mixture. Using a number seven tip in the pastry bag, pipe one inch circles of the mixture onto a silpat or parchment paper lined baking sheet. Bake for 30-40 minutes until lightly colored. Turn off the oven, leave cookies in the oven for 20 minutes. Remove from oven to cookie racks and allow the cookies to cool completely. Store in an air tight canister. Makes about 24 cookies.
