Mongolian Airag Butter Cookies
These delicate butter cookies are infused with the unique, slightly tangy flavor of Airag (fermented mare's milk), a traditional Mongolian beverage. The Airag lends a subtle complexity and tenderness to the classic buttery shortbread, creating a distinctive cookie that is both familiar and novel.

๐ง Ingredients
- 225 g Unsalted butter, softened
- 100 g Powdered sugar
- 30 ml Airag (fermented mare's milk)
- 1 tsp Vanilla extract
- 300 g All-purpose flour
- 50 g Cornstarch
- 0.5 tsp Salt
๐จโ๐ณ Instructions
- 1
In a large bowl, cream together the softened butter and powdered sugar until light and fluffy.
๐ก Tip: Ensure the butter is truly softened, not melted, for the best texture. - 2
Beat in the Airag and vanilla extract until well combined. The mixture might look slightly curdled due to the Airag, which is normal.
๐ก Tip: Use good quality, fresh Airag for the best flavor. - 3
In a separate bowl, whisk together the flour, cornstarch, and salt.
๐ก Tip: Sifting the dry ingredients can help prevent lumps. - 4
Gradually add the dry ingredients to the wet ingredients, mixing on low speed until just combined. Do not overmix.
๐ก Tip: Overmixing can develop the gluten in the flour, resulting in tougher cookies. - 5
Divide the dough in half. Shape each half into a log about 5 cm (2 inches) in diameter. Wrap each log tightly in plastic wrap and refrigerate for at least 30 minutes, or until firm.
๐ก Tip: Chilling the dough makes it easier to slice and prevents the cookies from spreading too much during baking. - 6
Preheat your oven to 160ยฐC (325ยฐF). Line baking sheets with parchment paper.
๐ก Tip: Parchment paper prevents sticking and makes cleanup easier. - 7
Unwrap the chilled dough logs and slice them into 1 cm (about 1/2 inch) thick rounds. Place the cookies on the prepared baking sheets, leaving about 2.5 cm (1 inch) between them.
๐ก Tip: Use a sharp knife for clean slices. - 8
Bake for 15-18 minutes, or until the edges are lightly golden brown. The centers should still be pale.
๐ก Tip: Bake time can vary depending on your oven; keep a close eye on the cookies. - 9
Let the cookies cool on the baking sheets for 5 minutes before transferring them to a wire rack to cool completely.
๐ก Tip: Allowing them to cool slightly on the sheet helps them firm up before moving.
๐ก Pro Tips
- โIf Airag is difficult to find, a small amount of plain yogurt mixed with a little milk and left to ferment slightly can be a substitute, though the flavor will differ.
- โFor a decorative touch, you can press a fork gently onto the top of each cookie before baking.
- โStore the cookies in an airtight container at room temperature for up to a week.
