2 c. shortening (no substitutes)
2 c. sugar
2 c. dark molasses
2 tbsp. ground cinnamon
2 tsp. baking soda
1 tsp. salt
9 to 10 c. all-purpose flour

In a 5-quart pan, heat shortening, sugar and molasses on low, stirring constantly until sugar is dissolved. Remove from heat; add cinnamon, baking soda and salt.

Stir in flour, 1 cup at a time, until dough can be formed into a ball. Using remaining flour, lightly flour a wooden board. Turn dough onto the board; knead until even in color and smooth (not crumbly or dry), adding more flour if needed. Form into a log. Cut into 5 equal pieces; wrap in plastic wrap.
