Reduced fat sour cream, 5%, has a thinner consistency and works much better in this recipe than full fat sour cream. The thin consistency is needed to bind all of the other ingredients together.
If making the lemon poppy seed scone, use only 1 heaping tablespoon of poppy seeds as the add-in. Also, add the lemon zest from one large lemon to the dry ingredients before mixing with the wet ingredients.
To make the glaze, combine 1 cup of confectioner's sugar with 2 tablespoons of lemon juice. Whisk together well. Drizzle over completely cooled scones.
