Preheat oven to 425⁰. Prepare a baking sheet with cooking spray or parchment paper.
To rehydrate the raisins, place them in a small bowl. Pour about 1 cup of boiling water over them and allow this to sit for about 15-20 minutes. Strain or squeeze excess water out of the raisins before adding them to the dough. You can use a strainer for this or cheese cloth.
Sift flour, salt, baking soda, cinnamon, cardamom, (allspice if using), and cream of tartar into a bowl. Stir in brown sugar. Using a pastry cutter or cold fingertips, cut the butter pieces into the dries until the pieces of butter are like small peas. Stir in the raisins, carrots and pecans. Mix well.
Add milk and vanilla all at once and mix just until integrated. Turn dough onto floured cloth or board and gather into a ball. You may need to absorb a little of the extra flour for this step, but be careful to not over handle your dough. Use a very light touch. Remember, as our British au pair once told me, “The keys to good scones are cold hands and a warm heart!” 💕
Roll or flatten the dough ball out to about 1 ¼ inch in thickness. Cut dough into 8 triangles for large scones, or 12 triangles for smaller scones. Or, you can also use a biscuit cutter dipped in flour if you prefer round scones.
Place scones on prepared baking sheet and refrigerate for approximately 10-15 minutes, or longer. Remove from oven and bake for approximately 12-14 minutes, or until the tops begin to turn golden-brown. Remove from oven and cool completely before icing.
