Preheat the oven at 180C degree. Line the baking tray with parchment paper. Now we should prepare bowl. You can use metal or any heat resistance ceramic bowls.
Take foil aluminium and cover the bowl with foil. Grease all over the bowl with veggie oil. Foil, will prevent the dough to stick to the bowl, otherwise our dough basket will break.
If you want to use a large bowl, use 2 piece of foil.

Place puff pastry on a floured surface. Roll it out longer. Use a pizza cutter or a knife and Cut the dough into strips.
Place dough strips crosswise (as you see in the photos).

Trim the edges. Press down the bottom by your hand or a glass or a bowl for the stability of the dough.

Next, we start to weave a pastry basket. Take one dough strip and weave your strips under and over each other and attach the ends together until to form your basket.

Press the dough on bottom edge. Place the bowl on the baking tray. Brush it with egg yolk. Place the basket in the oven to bake for 30 minutes.

Now baskets are ready. Take them out from the oven and allow to cool down. Take out the bowl and the very easily remove the foil.
Voila, look at these gorgeous bread baskets.
