The next step of the recipe is to stir two beaten eggs into the mixture using a wooden spoon.
I mixed my eggs together before I started combining my dry ingredients, so it was easy to grab them and mix them in.
After that, it was time to add buttermilk, again using a wooden spoon to stir the ingredients together until it created "a sticky mass." The recipe notes that you should add an additional teaspoon of buttermilk one at a time if the mixture doesn't have the right consistency. I ended up having to add one additional teaspoon to my dough before it seemed right.
Stirring everything together was definitely the most challenging part of the recipe, because the dough was firm thanks to all the butter. My arm started to get sore, and I had to take a few breaks as I stirred.
I also thought I was done once or twice, and then realized there was loose flour at the bottom of the bowl that hadn't been incorporated into the mass. I think if I had a bigger spoon, I might have had an easier time mixing it all together.
