Because this recipe makes quite a few, I offer you some advice: first, don’t underestimate how many people will eat. They will eat many. Second, they’re easily freezable and you can keep them pre-cut in the refrigerator for up to 5 days and pull them out whenever a craving strikes. Sam has made these with currants instead of raisins and even added a little citrus zest. These are a forgiving biscuit. Sam laughed as he watched me make them because I was being quite precise with the flour measurements. These aren’t a moody dessert. Don’t fuss over them. Don’t stress over them. They’ll turn out just fine.
Cream the butter and sugar together until light and fluffy, about 2-3 minutes. Add the egg and milk, and mix until combined. The mixture will seem chunky at this point, but don’t worry it will smooth out once you add the dry ingredients.
In a medium-sized bowl, whisk together all of the dry ingredients, excluding the raisins.
Add the dry ingredients to the wet ingredients and mix until combined. At the very end, add the raisins and stir just long enough to incorporate them into the dough. Gather the dough into a ball, wrap in plastic wrap, and chill for one hour. After chilling, roll the dough out about 1/2 inch thick on a well-floured board. Cut into shapes with a sharp cookie cutter.
Lightly brown the biscuits on a hot, greased griddle or skillet, about 30 seconds-1 minute per side. Serve warm.
