Apfelstrudel

Stir the flour and salt, then add the warm water, oil, and vinegar and bring it together. Knead 10 minutes to an unusually smooth dough. Then pick it up and throw it down hard against the counter, fold, and throw again, 30-50 times. The throwing is traditional and it works: it aligns and strengthens the gluten faster than kneading alone.

Look for Smoother than any bread dough you have made: soft, satiny, almost polished, and a pinch stretched thin passes the windowpane test easily.

Coat the ball generously in oil, set it on a plate, and cover it with a bowl you have warmed under hot tap water and dried. Rest 60-90 minutes at room temperature, or overnight in the fridge (bring it fully back to room temperature before stretching).

Look for The rested ball slumps and spreads slightly, and a fingertip dent stays put. That slackness is the stretch, banked.

Clear the table, lay the cloth over it, and rub flour into the weave with your palm, everywhere the dough might reach. Take off rings and watches, and roll sleeves past the elbow.

Look for A taut, evenly floured cloth with no bare patches; the dough should glide on it, never grab.

Roll the rested dough on the cloth into a disc the size of a dinner plate. Now flour your hands, slide them under the sheet palms-down, and stretch from the center outward over the backs of your hands, letting the dough's own weight hang and thin itself over your knuckles. Work around the table in a circle, always pulling from the thicker center toward the edge, until the sheet reaches about 24 x 30 inches.

Look for The old Viennese test: you should be able to read a love letter through it. A newspaper headline through the sheet on the cloth settles it. The sheet should billow like fabric as you work, with a thicker rope of dough only at the very rim.

Cut the thick rim off all the way around with scissors and set the trimmings aside. Leave any small tears alone; the rolling buries them without a trace. Press a flattened piece of trimmed dough gently over any hole bigger than your palm.

Look for An even, translucent rectangle edge to edge, patches pressed thin enough to vanish. Small tears genuinely do not matter; keep moving.

Warm the rum in the small saucepan until it steams, pour it over the raisins in a small bowl, and let them sit 30 minutes. Drain them in the sieve just before the final toss.

Look for Raisins swollen glossy and round, their wrinkles half gone, with barely a spoonful of rum left unclaimed in the bowl.

Toast the walnuts in the dry skillet over medium, tossing, 4-5 minutes, then chop them roughly and let them cool.

Look for A shade darker and loudly fragrant, with a dry rattle when the pan shakes.

Melt the 40g plant butter in the skillet over medium, add the breadcrumbs and a pinch of the salt, and toast, stirring without stopping, 4-5 minutes to a deep gold. Cool them fully; hot crumbs on a thin sheet is a hole.

Look for Deep, even gold, smelling of toast and browned fat, dry enough to scatter loose from your fingers.

Peel, quarter, and core the apples, then slice them a scant 1/8 inch (3mm) thick, tossing the slices with the lemon juice in a large bowl as you go. No sugar yet.

Look for Slices thin enough to flex without snapping, pale and glossy from the lemon, with no browning anywhere in the bowl.

Only when the sheet is stretched, trimmed, and brushed: toss the lemoned apples with the sugar, cinnamon, zest, and remaining salt, then fold in the drained raisins and the walnuts.

Look for Slices dusted matte with the cinnamon sugar and no liquid pooling in the bowl. If juice is gathering, you waited too long; tip it off before filling.

Working quickly, brush the whole stretched sheet with about two-thirds of the melted butter in a thin, even film, starting at the edges, which dry first.

Look for The sheet turns glossy and supple and stops threatening to dry; you should still see the cloth's weave through it.

Scatter the cooled crumbs in a band about 6 inches deep across the near end of the sheet, leaving a 2-inch border at the near edge and sides. Spoon the just-tossed apple filling over the crumbs in an even layer.

Look for A tidy, even band: crumbs fully hidden under fruit, raisins and walnuts distributed so no slice will come up empty.

Fold the side borders in over the filling. Then grip the cloth at the near edge and lift: the strudel rolls over onto itself. Keep lifting and walking the cloth forward, letting each turn roll snugly onto the last, until the sheet is fully wrapped. Steer with your hands; let the cloth do the carrying.

Look for An even log with four or five translucent wraps and the seam finishing underneath. You should never have lifted the pastry itself, not once.

Use the cloth to roll the strudel onto the parchment-lined sheet pan, seam underneath, curving it into a gentle horseshoe if it runs long. Tuck the open ends under to seal, and brush the whole surface with butter.

Look for Seam hidden beneath, ends tucked, the surface glossy from the brush end to end.

Bake at 375°F (190°C) for 40-45 minutes, brushing with the remaining butter at the 25-minute mark, until deep gold and audibly crisp.

Look for Deep gold with darker ridges where the wraps overlap, apple juice bubbling thickly at the tucked ends, and a crackle when you tap the crust with the brush handle.

Rest 25-30 minutes on the pan. Dust with powdered sugar, then slice with the serrated knife in a gentle saw, on the diagonal.

Look for Cut, the layers stand in visible flakes, the apples hold as soft, translucent slices in a loose jam, and the raisins sit glossy in the seams.
