Parrozzo

Parrozzo is a dome of almond-and-semolina cake, eight or nine centimetres high, entirely coated in dark chocolate. Inside it is deep yellow, moist and close-textured; outside it is dark and snaps.

The ingredient list is short and every item shows in the result: eggs, and above all yolks, which supply the colour; finely ground sweet almonds with a small proportion of bitter almonds for the marzipan perfume; semolina, which gives a faint grain; sugar and butter. There is no wheat flour, no yeast and no candied fruit.

The shape is a quotation. Parrozzo was built to echo pane rozzo, the rough maize loaf Abruzzese farmers baked in wood ovens: domed, yellow inside from the cornmeal, with a crust blackened by the fire. The pastry chef who invented it rebuilt the yellow with egg yolks and semolina, and the burnt crust with chocolate.

It is an authored cake with a precise birth date, 1920, which makes it an outlier in a category otherwise made up of recipes with no parent. And unlike almost every Italian celebration sweet, it is not tied to a single feast: it is eaten year-round, with a sharp peak at Christmas, when it becomes the standard gift from Abruzzo.

Almond first and almond last. The base flavour is the same as good marzipan or a French financier (rich, toasted, slightly bitter at the edges) lifted by the small dose of bitter almonds that gives it an amaretto perfume without any of the sweetness of amaretto liqueur.

The chocolate arrives before the crumb does, since you bite through it: dark, mildly bitter, thin enough to snap rather than to chew. It is doing a job beyond flavour, cutting the richness of the almonds and keeping the cake from reading as one-note.

Texture is where the semolina shows. The crumb is moist and dense, with a faint sandy grain that separates it from any sponge cake. It is closer to a very good almond torte than to layer cake, and there is no leavened lightness at all.

Sweetness is moderate. What lingers is the almond oil and the bitterness of the chocolate, which is why a small slice satisfies.

Cut it into wedges like a cake, using a smooth blade warmed under hot water and dried, or the chocolate shell cracks. Sixty or seventy grams is a portion.

Serve it at room temperature. Cold from the fridge the crumb tightens and the almond flavour goes quiet; twenty minutes out puts it right.

It works at both ends of the day. In Abruzzo a morning slice gets dunked in milk, and an evening slice comes with a glass of sweet wine or a spirit.

It makes an excellent base for something else. Crumbled into a glass with sweetened ricotta and grated orange zest it becomes a spoon dessert; sliced thin and warmed for a moment it holds a scoop of almond gelato.

One thing to avoid: never reheat it in the oven. The coating melts, runs and recrystallises dull, and the cake loses its only decorative surface.

It keeps at room temperature, somewhere cool and dry, for two or three weeks while it is still in its wrapper, and the wrapper is doing real work. Once you cut it, press film against the cut face and finish it over five or six days, because the exposed crumb dries very fast: semolina holds less water than flour, so the surface goes sandy within a day or two and the almond aroma fades with it. The date on a boxed one belongs to the producer.

The fridge is the wrong place. Cold tightens the crumb, mutes the almond and brings the cocoa butter to the surface of the coating as white streaks, which is a permanent cosmetic change once it has happened. Above 25 C the chocolate softens and takes fingerprints, so in summer it wants the coolest spot in the house rather than the fridge. It freezes whole and well wrapped for three months, and it should thaw slowly at room temperature still in its wrapping: unwrapped cold, condensation settles on the chocolate and dulls it.

Cut it and look at the crumb: it should be a full yellow verging on orange, which is what a lot of yolks look like. A pale parrozzo was made with fewer eggs and more semolina. The bite has to carry a grain, a barely perceptible roughness from the semolina that is exactly what separates this from a sponge cake; smooth and velvety means the recipe was lightened with flour or starch. Bitter almond should be there and stay in the background, and when it leads and smells synthetic, almond flavouring has replaced the bitter almonds themselves, which is the usual shortcut.

The coating is real dark chocolate, thin and glossy. A thick dull layer that marks under your thumb at room temperature points to a compound coating with vegetable fats in place of cocoa butter. Shape settles the rest: a clean dome, not a truncated cone and not a loaf. The rectangular parrozzo that turns up in some supermarkets is a chocolate cake that borrowed the name, and outside Italy the cake is essentially only found in Abruzzese food shops or shipped from the producers in Pescara.

Artisan parrozzo runs 18 to 30 euro a kilo in Italy. The standard 500 g dome costs 12 to 18 euro in a pastry shop, with Christmas gift boxes adding three or four euro for packaging.

Almost all of the price is almonds (a correct recipe runs to well over a third of the weight) and couverture chocolate. Industrial versions below twelve euro a kilo cut both: less almond, more semolina, flavouring instead of bitter almonds, and a compound coating made with vegetable fat rather than cocoa butter. You can feel the difference in the coating with your fingers before you taste anything.

Abroad, Italian delis and online grocers list it at roughly 16 to 26 dollars a pound in the US and 25 to 40 pounds a kilo in the UK, with the widest availability in December. It ships well: the chocolate shell protects the crumb and the cake keeps for weeks.

Check the shape before you buy. A rectangular loaf sold as parrozzo is a chocolate cake wearing the name; the real thing is always a dome.

Pescara, where it was invented and where every pastry shop in the centre makes one. The firm founded by Luigi D'Amico is still trading and is the historic reference point, but tasting two or three versions side by side is the best way to understand how much the almond percentage matters.

Pescara takes a day: the seafront, the Ponte del Mare, and above all the house where Gabriele D'Annunzio was born, now a museum, which closes the loop with the cake's own story.

Chieti and the Teatina coast south of the city have their own versions, some with a higher almond content and a thinner coating.

December is when parrozzo fills every window in Abruzzo, because it is the regional Christmas gift by default: you will find it in motorway service stations and railway kiosks in gift boxes.

While in the region, line it up against the other two Abruzzese sweets that define the place: the sugared almonds of Sulmona, in the Peligna valley, and ferratelle, the iron-pressed wafers made in every inland village.
