1 large hen, coiled in salt water until tender. Either cut real fine or grind it up. Add to the broth 1 small onion and boil until the onion is done. Strain broth and add 1 package Knox unflavored gelatin, dissolved in 1/2 cup cold water. There should be 1 1/2 cups broth if not, add sufficient water to make that amount. Pour this over chicken to which has been added 3 pimentos and juice of 1 lemon. Let set until congealed.
