Persimmon Strudel

Go through the dough ingredients and you'll see it's built exactly like a good sweet pastry for a tart, because that's what it is. Plain flour, not strong bread flour — you don't want gluten development here, you want structure from butter, not elasticity from protein. Icing sugar rather than caster in the dough itself: it dissolves without needing to be creamed in, so the dough stays short instead of being beaten into something stretchy. The whole egg plus three extra yolks is for richness and a bit of binding fat without adding excess water — yolks carry fat and flavour, whites carry water and toughness, so three yolks and only one white skews the whole dough toward tender. Butter cold, cut in rather than melted, is non-negotiable for the reason above: it needs to stay in separate pieces through the flour so that when it bakes, each speck melts and leaves a tiny gap of steam behind it, which is what "short" actually means on the tongue. Lemon zest is there for scent, not acidity — a strip of orange zest would do the same job if that's what's in the fruit bowl, since there's already orange jam in the filling to tie the two together. The pinch of salt is seasoning, full stop — pastry without any salt tastes flat and sweetish in a way people struggle to name but definitely notice.

For the filling, persimmon wants to be the firmer, non-astringent kind if you can get it — in the UK that's usually labelled Sharon fruit, and it holds its shape under heat rather than collapsing into syrup the way a very ripe, jammy persimmon would. If persimmon isn't in season or in the shop, you're really looking for any fruit that's sweet, holds structure when warmed, and isn't too wet — a firm pear or a tart apple, diced the same way, would behave similarly, though you'd lose the persimmon's particular honeyed note. Orange jam gives moisture and a citrus backbone; marmalade with the peel strained out, or apricot jam, covers the same job — something that spreads like a glaze and ties the diced fruit together rather than a loose, runny jam that would soak the pastry. Walnuts should be chopped fine but not to dust — you want crunch distributed through the filling, not a flavour note; any nut that isn't oily enough to turn rancid quickly works, pecans or hazelnuts both substitute cleanly.

The melted butter and brown sugar brushed and scattered on top before baking aren't decoration. The butter helps the surface colour evenly and gives you that faint shine; the brown sugar, with its bit of molasses, caramelises at a lower point than white sugar and gives you a thin crackled crust rather than a flat, dry top. Icing sugar only goes on after baking, dusted once it's cooled — do it hot and it just melts into a wet smear, which is a small, common mistake with no real recipe fix, just patience.

One real limit of an ordinary UK kitchen: 180°C no fan means you're trusting your oven's actual temperature, and most domestic ovens drift by ten degrees or more from the dial. If after the stated time the pastry is pale and the filling still looks wet rather than slightly bubbled and set at the edges, that's your oven running cool, not the recipe being wrong — give it longer and trust the look of it: golden, with the seam showing a faint set gloss rather than a raw shine, matters more than the clock.

This feeds four generously as a pudding, which in the UK context means it slots in nicely after a Sunday roast — it's rich enough that nobody needs a large slice, and it sits well with a pot of tea with milk rather than anything stronger, since the orange and persimmon already carry plenty of sweetness on their own.
