1Preheat oven to 375 degrees F (190 degrees C). Lightly grease cookie sheets.
2In a large bowl, stir together the sugar, ginger, nutmeg, cinnamon, salt, and baking soda. Mix in the melted margarine, evaporated milk, molasses, vanilla, and lemon extracts. Stir in the flour, 1 cup at a time, mixing well after each addition. The dough should be stiff enough to handle without sticking to fingers. If necessary, increase flour by up to 1/2 cup to prevent sticking.
3When the dough is smooth, roll it out to 1/4 inch thick on a floured surface, and cut into cookies. Place cookies on the prepared cookie sheets.
4Bake for 10 to 12 minutes in the preheated oven. The cookies are done when the top springs back when touched. Remove from cookie sheets to cool on wire racks.
