   ["Bake the pastries: Preheat oven to 425 degrees F. Take 1 sheet of puff pastry and lay out flat on a lightly floured working surface, with the long side facing you. Following the folding lines, cut in 3 pieces lengthwise and then each piece cut in 4 equal pieces. Repeat with the other sheet of puff pastry, so you have 24 equal pieces.", "Bake on two cookie sheets lined with parchment paper. Before transferring to the oven, duck each piece of pastry all over with a small fork. Bake 10 minutes; then reduce temperature to 325 degrees F and bake for 30 to 35 minutes more (pastry should be baked through and deep golden-brown). Cool on a wire rack to room temperature.", "To make the pastry cream: Scrape the seeds from the vanilla bean. In a heavy saucepan, combine milk, vanilla bean and seeds, and 1/2 cup sugar. Scald the mixture and immediately remove from heat.", "Beat egg yolks with remaining 2 tablespoons sugar until thick. Sprinkle in cornstarch and continue beating until mixed.

   Beat half of the hot milk into yolk mixture. Return this to the remaining hot milk and bring to a boil quickly, whisking very fast to prevent scorching. Remove from heat and strain into a bowl to cool. Discard vanilla bean.", "Cover with plastic wrap, pressing directly on the surface of the pastry cream to prevent a skin from forming. Transfer to the refrigerator to chill completely. Can be made 2 to 4 hours in advance.", "Puree avocados, lime zest and juice, salt and butter in a food processor until very smooth. Just before using, gently fold in with a spatula into the chilled pastry cream until fully incorporated.", "To assemble: using a pizza cutter or a sharp knife, cut off very thin strips from all four ends of each pastry piece, this step will make them even and dispose all layers of the puff pastry, (reserve all the scraps, which you cut of).", "Spread 1 tablespoon of the avocado pastry cream on a piece puff pastry, place another pastry piece and spread the top with 1 more tablespoon of the cream; repeat the same process with all the remaining pastry pieces; return to the wire rack and place in refrigerator for 1/2 hour to set.", "In a food processor combine nuts and the puff pastry scraps, pulse a few times until coarse crumbs form. Evenly sprinkle over the tops of each of the pastries and then dust with confectioner's sugar. Serve as soon as possible; otherwise the puff pastry absorbs moisture and becomes soft."]
