⭐ Buttermilk (Best Fat-Free Option)
3/4 cup buttermilk per 1 cup Greek yogurt Quick tip: Buttermilk adds acidity but is thinner, so reduce other liquids slightly to maintain dough consistency.
Buttermilk is acidic like Greek yogurt, which helps with leavening and flavor development in scones. However, it is much thinner, so using it in a 1:1 ratio would make the dough too wet. Reducing the amount to about 75% of the Greek yogurt volume helps maintain the proper dough texture.
When substituting, reduce other liquids in the recipe slightly or add a small amount of flour to compensate for the extra moisture. Mix gently to avoid overworking the dough.
The final scones will be tender and tangy but may have a slightly lighter crumb and less richness compared to Greek yogurt.
