Preheat the oven to 350°F.
Prepare a baking sheet with parchment paper and set aside.
In a small sauce pan on a medium heat, add raisins to water and bring to a boil, ( this will plump up the raisins ).
Once the raisins are plump, remove from heat, drain the water, and set aside to cool.
Add lemon juice and the plant based milk together in a measuring cup, stir just enough to combine, set aside.
In a medium mixing bowl add the flour, baking powder, sugar, cinnamon, and salt.
Stir the dry ingredients together, then add the margarine and blend together with a pastry cutter or fork until the dough resembles a sandy texture.
Pour in the vegan buttermilk and stir until everything is well combined, the dough will not stay together yet, it should be a lumpy dough.
Next add the cooked raisins and mix in with your hands to evenly distribute through out the dough.
Continue by lightly dusting the counter top with flour, place the dough on to the flour and knead the dough a few times until the dough stays together.
Pat the dough down into a 1/2 inch thick circle.
Cut the circle into triangle shapes and arrange the pieces on the parchment paper.
Place the filled baking sheet into the oven and bake for 24 minutes.
After 24 minutes, remove the baking sheet from the oven, leaving the scones on the baking sheet to cool slightly before serving.
Serve your scone with a vegan margarine, jam or jelly, or a vegan cream cheese.
Once the scones have cooled completely, store in a air tight container for later.
If you would like to reheat the scones, place in a toaster oven for a few minutes before serving.
