( The corn starch is to slightly thicken any water 💦 released by 🍏🍎 apples and frozen berries. Turn on-stove to med heat same, if using a portable stove, place a large pot or skillet adding two Tbsp of unsalted butter, cook and stir apples until apples mix are almost tender then add frozen raspberries to warm up for One minute to release water and slightly stir all the apple 🍏 🍎 mixture – turning off stove.

Let cool a little abit then add to one puff pastry rolled out the pastry dough on a buttered parchment paper 📝 📑 to avoid sticking. Place the parchment paper on an upside down baking metal pan then roll out the dough then add apple mix – all along one side – into two inch in the pastry dough to roll up the whole apple mixture leaving room to pinch together each end piece of the dough pastry and keep rolling pastry dough or home made pastry dough until 1/2 inch of pastry is left than brush or spoon on one egg mix together with abit of milk Or use an already egg mixture in a carton to glue the last part of pastry to the rolled up pastry dough. Then pinch each end piece and once done than spread egg mixture all over the rolled up pastry dough but, do not do bottom part of dough. It can get a little messy> have a paper towel to wipe off any wetness from your hand while pinching together each end side. Then
On the top before adding egg mixture, make two small slits with kitchen scissors cutting in two places to let steam release while baking in the oven at 350 for 25 minutes and it's nice and golden brown. Then once cooled- it can be sliced
