Torta di Grano Saraceno

Buckwheat reached the Alps centuries ago and took hold precisely where wheat struggled, in the thin, high soils of valleys like the Venosta; the name grano saraceno, «Saracen grain», records that it was understood to have come from the lands of the East rather than from local fields. In South Tyrol the grain is woven through the old cooking — as the dark polenta called Schwarzplenten and in buckwheat dumplings — and buckwheat flour itself is a recognised PAT of the province. The cake is a traditional Alpine bake built on that heritage, shared with the Austrian Tyrol across the border; it is a regional home cake rather than a protected or precisely codified product, so accounts of its filling and method vary from valley to valley.

The cake is dry-edged and crumbly rather than moist and springy — it breaks into tender, sandy crumbs and is meant to, the ground almonds and buckwheat keeping it short. The buckwheat lends a gentle earthy, nutty flavour under the sweetness, and the lingonberry jam through the middle is sharp and fruity, cutting the richness of the butter and nuts. A snow of powdered sugar on top is the only finish. It is unshowy, slightly rustic eating: not a light, airy cake but a substantial, comforting slice best with coffee or tea, when its dryness is a virtue rather than a fault.

Buckwheat is not a true cereal and has no gluten, so the cake cannot rely on a gluten network for structure — it holds together through egg and the starch and protein of the buckwheat and almonds, which is exactly why the crumb is short and tender rather than chewy. The lift comes mostly from whipped egg whites folded into the batter: the air beaten into the whites expands in the oven and sets, raising a flour that could never rise on gluten alone. Creaming butter with sugar traps still more air. Ground almonds add fat and moisture that keep the otherwise dry buckwheat crumb from turning hard. The cake is cooled fully before it is split and filled, so it does not crumble apart, and the acidity of the lingonberry jam balances the sweet, nutty cake.
