Preheat oven to 375 degrees. Lightly grease a baking sheet, or line it with parchment.
In a large bowl, whisk together the flour, salt, sugar, nutmeg, and baking powder.
Cut the butter into small pieces. Using a pastry blender cut the butter into the dry ingredients.
In a separate bowl, whisk together the eggs, yogurt or sour cream, almond extract and heavy whipping cream.
Stir the wet ingredients into the dry ingredients.
Add the peaches, stirring just until everything is combined. This is a wet, sticky dough.
Drop the dough by the 1/4-cupful onto the prepared pan; a muffin scoop works well here.
Sprinkle with the coarse sparkling sugar, if desired.
Bake scones for 20-25 minutes, until they're light golden brown. Remove them from the oven, and let them cool on the pan for a few minutes before transferring to a rack to continue cooling.
Serve warm, or at room temperature. Store at room temp., well wrapped, for several days.
