To make this recipe gluten-free, replace the all-purpose flour with a gluten-free 1:1 baking flour blend suitable for pastries.
Confirm that the baking powder, baking soda, currants or raisins, buttermilk, and heavy cream are labeled gluten-free.
Gluten-free scone dough may be slightly more delicate, so handle it gently when shaping and cutting.
Chilling the shaped dough is especially helpful for gluten-free scones because it helps them hold their shape.
Use a clean work surface, utensils, and baking sheet to prevent cross-contamination.
