This danish pastry is simply the best dough to have on hand for yummy jam or cheese-filled danish desserts. The result will be golden brown, buttery, and flaky perfection.
Warm 1/2 cup of milk to 110°F. Combine warmed milk with yeast and sugar, let it sit for 10 minutes until the yeast blooms.
In a separate dish, add remaining 1/2 cup of milk and egg. Whisk until well combined.
Into a separate large bowl, add flour and salt. Grate frozen butter on the large side of a grater. Toss butter with flour as you grate it in.
Add all the liquid ingredients to the butter/flour mixture. Using a spatula, stir to combine together until you have everything combined. Dough may look rough and sticky, that is normal.
Cover the bowl with a wrap and refrigerate for at least 6 hours.
Sprinkle the working surface lightly with flour. Roll out the dough into a rectangular shape, about 1/3 inch thick. Fold dough over like a paper, then roll again to 1/3 inch thick. Repeat 3 times until you reach smooth dough. Work quickly to prevent butter from melting.
Place plastic wrap or parchment paper on the dough and fold it over. Leave to refrigerate for at least 2 more hours.
