• In a mixing bowl, whisk the egg yolks and granulated sugar until they are well combined.
• Next, incorporate the sour cream, mayonnaise, and honey, blending thoroughly until the mixture is smooth.
• In a separate bowl, combine the all-purpose flour and baking powder.
• Gradually add the dry mixture into the wet ingredients, mixing until fully combined. If the dough is sticky, that's completely normal. Cover and refrigerate for a minimum of 2 hours.
• After the chilling period, use a spoon to scoop out portions of dough and gently roll them into balls using slightly damp hands.
• Set your oven to preheat at 350°F. Arrange the dough balls on a baking sheet and bake for about 15 minutes until golden brown. Allow them to cool on a rack after baking.

For Glazing:

• In a bowl, mix the pasteurized egg whites with powdered sugar until a thick glaze forms.
• Generously apply the glaze over each cookie, ensuring to coat the bottom as well. Let the cookies sit at room temperature until the glaze has dried completely. Enjoy your delightful Pryaniki cookies!
