Panettone is the great Milanese Christmas bread — and one of the most technically demanding baked goods in the entire Italian repertoire. It is a tall, dome-shaped, butter-enriched bread studded with candied citrus peel and raisins, with a soft, feathery, almost cotton-like interior structured by long strands of developed gluten and enriched with extraordinary quantities of butter and egg yolks. The technique revolves around the lievito madre (mother dough/natural levain) — a stiff sourdough starter that must be maintained through regular refreshments for weeks or months before the panettone season. The production takes 2-3 days: the lievito madre is built up through multiple refreshments over 24 hours, then incorporated into a first dough (primo impasto) with flour, sugar, egg yolks, and butter. This first dough ferments for 10-14 hours. Then a second dough (secondo impasto) adds more flour, sugar, egg yolks, butter, candied fruit, and raisins. After a final mixing, the dough is divided, shaped into balls, placed in tall paper moulds (pirottini), and left to prove for 6-10 hours until the dough has risen to the rim of the mould. The baking is precise: 170-180°C for 50-60 minutes for a 1kg panettone, with the internal temperature reaching 94°C. Immediately after baking, the panettone is inverted and hung upside down on skewers to cool — this prevents the heavy dome from collapsing under its own weight as it cools. The result, when properly made, is a bread of extraordinary lightness despite its richness: the interior pulls apart in long, soft, aromatic strands, and the flavour is of butter, vanilla, citrus, and a subtle tang from the natural levain. Industrial panettone and artisanal panettone are almost different products — the industrial version uses commercial yeast and takes hours instead of days, producing a denser, less complex result.

Maintaining a lievito madre for panettone is a year-round commitment — serious bakers refresh their starter 2-3 times per week year-round, then daily in the weeks before Christmas. The butter must be of the highest quality: 82%+ fat, European-style. The candied fruit should be made by a serious confectioner — the industrial cubes found in supermarkets are a different product; seek out whole candied orange and citron peel and dice it yourself. The inversion cooling technique works by allowing gravity to keep the structure stretched while the starches set — without it, the weight of the butter and eggs compresses the still-soft interior. Temperature control during fermentation is critical: 26-28°C is the sweet spot for the lievito madre; warmer produces excessive acidity, cooler stalls the rise. A properly made artisanal panettone stays fresh for 5-7 days without preservatives — the natural levain and high butter content act as natural preservatives.
Using commercial yeast instead of lievito madre — the natural levain provides both structure and the characteristic subtle tanginess. Under-developing the gluten — panettone dough must be mixed until the gluten creates long, elastic strands; under-mixed dough collapses. Not inverting after baking — the dome collapses within minutes if left upright while hot. Using insufficient butter — the richness requires 20-25% butter by flour weight; less produces a bready, dry result. Rushing the fermentation — each stage requires its full time; shortcutting produces dense, flat panettone. Overfilling the moulds — the dough should fill 2/3 of the mould before proving.
