Dark corn syrup,
Roll chilled dough into rolls about the width of a finger. Cut with a knife into small 'pillows'. Pat pillows flat and bake in moderate oven (350 degrees? ~- time is unknown so I'd have to guess maybe 8-10 minutes. This is an old recipe of my grandmothers and it doesn't specify).
Boil the Karo syrup for 2 minutes, and then add the sugar, butter, and salt. Stir until sugar and shortening are melted, then cool. When cool, add remaining ingredients (except flour). Add flour in increments until dough is very stiff. Chill thoroughly (can even be frozen).
Instead of 1 c butter and 1 c of lard, you can use 2 cups shortening instead.
