Kastanienstrudel

Every October, the Grünmarkt in Salzburg smells like roasting chestnuts. The Maroni stands appear as if on cue, paper cones piled high, and for a few golden weeks the whole city tastes like autumn. Kastanienstrudel is what happens when that season meets the Mehlspeisen tradition, and it's one of the things I look forward to all year.

Gretel always said chestnuts were the most generous nut. They give you sweetness, body, and a kind of velvet richness that almonds and walnuts can't match. She used to roast them in Eva's kitchen in Kent, split across the top so they wouldn't explode in the oven (a lesson she claimed to have learned the hard way in 1952). Then she'd peel them while they were still hot, swearing quietly in Viennese German, and push them through a ricer into a bowl with rum and sugar and a scrape of vanilla. That puree is the heart of this Strudel. It's dense and fragrant and the color of burnished wood.

The dough is the same hand-stretched dough you'd use for Apfelstrudel. Flour, water, oil, a splash of vinegar, rested until it relaxes, then pulled across a floured cloth until you can read a newspaper through it. The filling goes on in a thick line along one edge, and you roll the whole thing using the cloth to guide it. When it comes out of the oven, the pastry is shatteringly thin and crisp, and the chestnut filling inside is soft and warm and faintly boozy. You dust it with powdered sugar and serve it with Schlagobers. That's all it needs.

This is not a summer Strudel. Don't try to make it in July. Wait for the chestnuts. Austrian cooking is seasonal and that's part of what makes it honest. When October comes and the first Maroni appear, you'll know it's time.
