1 cup Milk, 2 1/4 tsp Active dry yeast
In a large bowl, mix the flour, sugar, and salt. Add the cubed butter and use a pastry kneader or your hands to knead the butter into the flour. Do this until the butter is the size of a pea.
4 3/4 cups All-purpose flour, 1/4 cup White granulated sugar, 1 tsp Salt, 10 TBSP Unsalted butter
In a small bowl, lightly beat the eggs. Pour the milk/yeast mixture, eggs, and lemon zest into the dry ingredients.
2 Large eggs, 2 Large lemons zested
Use a stand mixer with a dough hook (make by hand instructions in recipe notes), and mix on low speed until a dough starts to form. Mix on medium speed and knead the dough for 5 minutes.
Spray a large bowl with non-stick spray. Place the dough in the bowl and cover with a kitchen towel. Let it rise for 1 hour. It will double in size.
