Step 1

Preheat oven to 375 degrees F and line with parchment paper a large baking tray. Set aside.

Step 2

Peel and core the apples and cut into about 1/2 inch slices. In a large skillet set over medium heat, add the butter until it melts. Stir in the 1/4 cup of sugar until you have a syrupy like consistency. Stir for just a couple of minutes. Add the apple slices and stir well. Leave the apples to cook for about 10 minutes stirring occasionally. Remove from heat and leave to slightly cool.

Step 3

Lay out your pastry on the parchment paper on the baking tray. Spread the apple mixture in the middle third leaving about a one inch border at the top and bottom. Cut the top two corners diagonally and then continue to cut strips on each side. You will get anywhere between 6 to 8 strips. Cut away excess pastry at the bottom. Once you have all your strips cut you can start folding them over. Starting at the top left, fold the strip down on a diagonal and then the right side. Continue doing this until you have folded over all the strips. Seal the top and bottom by pulling together the pastry at the ends to meet. Gently press together. Brush with the egg wash and then sprinkle with remaining 1 tablespoon of sugar.

Step 4

Bake in the preheated oven for about 20 minutes. Remove from oven and leave to cool to room temperature.

Step 5

Make the glaze by combining the powdered sugar and milk. Whisk until combined. Drizzle over the cooled Danish. Serve at room temperature or even cold. Will keep for a few days.
