Heat oven to
350F (175C). Grease and flour a large cookie sheet. Beat egg whites and
salt until soft peaks form. Add sugar gradually, beating well after each
addition. Beat until stiff and glossy. Beat egg yolks and vanilla until
thick and lemon colored. Add to egg whites and fold in gently but quickly.
Fold in flour. Press through a pastry tube or cookie press with a large
plain tip into strips 2 1/2 inches (6.25cm) long onto prepared cookie
sheet. (If you don't have a pastry tube or cookie press, shape rounded
teaspoonfuls of batter into strips). Bake 8-10 minutes or until set and
very lightly browned on the bottom. Remove from sheets and cool on racks.
Store in tightly closed tin box.
