In a large bowl, mix together the white sugar, molasses, and shortening until well combined.

Add the buttermilk and mix until smooth.

In a separate bowl, whisk together the soda, cinnamon, ginger, and salt.

Gradually add the dry ingredients to the wet ingredients, mixing until just combined.

Continue adding flour until the dough becomes stiff enough to roll out.

On a lightly floured surface, roll the dough to your desired thickness (approximately 1/4 inch).

Use a cookie cutter (round or other shape) to cut out the cookies.

Place the cookies on a baking sheet.

Sprinkle the tops of the cookies with granulated sugar.

Place a raisin or a small amount (tsp) of jam on top of each cookie.

Bake in a preheated 350°F (175°C) oven for 10 minutes, or until the edges are lightly golden brown.

Remove from oven and let cool completely before serving.
