The pastis gascon (or croustade gasconne aux pommes) is Gascony’s most spectacular pastry — a multi-layered apple pie whose tissue-thin pastry sheets are stretched by hand over a cloth-covered table to near-transparency, then brushed with Armagnac-scented goose fat and layered around Armagnac-macerated apples into a towering, crunchy, golden dome. The pastry technique is essentially identical to strudel dough and has the same Central European origins via medieval trade routes. The dough is deceptively simple: 300g flour, 1 egg, 60ml warm water, 30ml sunflower oil, a pinch of salt — kneaded vigorously for 10 minutes to develop the gluten that allows extreme stretching, then rested under a warm bowl for 1 hour. The stretched dough should be transparent enough to read newsprint through it. The filling combines 6-8 firm apples (Reinette or Golden), peeled and sliced thin, macerated for 2 hours in 100ml Armagnac with sugar (150g) and vanilla. Each sheet of stretched dough is brushed generously with melted goose fat (200g total), then layered in a buttered mold or arranged free-form on a baking sheet, the apple filling distributed across the layers. The top sheets are gathered and ruffled to create an ornamental dome that crisps and caramelizes in the oven at 190°C for 35-40 minutes. The result is a masterwork of textural contrast: shatteringly crisp, almost gossamer layers of fat-brushed pastry encasing tender, Armagnac-perfumed apples. Each bite releases a shower of golden flakes. This is the dessert of Gascon celebration — weddings, harvest feasts, and the return of the oie grasse (fattened goose) season.
Hand-stretched dough (flour, egg, water, oil) to near-transparency. Rest dough 1 hour after kneading. Brush each sheet with goose fat. Apples macerated in Armagnac 2 hours. Layer dough and filling, create ruffled dome. Bake at 190°C for 35-40 minutes.
Work on a large cloth-covered table, well-floured, and stretch with the backs of your hands (fingers poke holes). The dough should hang over the table edges without tearing. Any thick edges are trimmed and discarded. For the finest result, use 8-10 layers. A dusting of fine sugar between layers creates additional caramelization. The pastis is best eaten warm, within 2 hours of baking, when the pastry is at maximum crispness. Serve with a small glass of Armagnac alongside.
Not kneading long enough (insufficient gluten development, dough tears). Rushing the rest period (gluten needs to relax for stretching). Using butter instead of goose fat (burns at the required temperature). Forgetting the Armagnac maceration (the spirit defines the Gascon character). Stretching in a cold room (dough is less elastic — warm room, 22-24°C).
