Sourdough panettone, home batch
A tall Lombard Christmas bread enriched with butter, yolks and candied citrus, raised first with refreshed sourdough and then proofed in a paper mould.
Modern method
Panettone · Overnight panettone
A modern instant-yeast panettone with an overnight flour-and-water preferment and mixed dried fruit. It is separate from specialist sourdough panettone methods.

Traditional-style specialist panettone can involve refreshed sourdough, successive enriched doughs and suspended cooling. That sequence belongs to its own formula. This household version uses an instant-yeast preferment without eggs, then adds enrichment the following day.
Its mixed dried fruit and flavouring options are a modern variation, rather than a claim to reproduce every Milanese panettone.
PJ Hamel's modern overnight formula, updated April 2026. The bread's Lombard association and a separate specialist sourdough method are documented by GialloZafferano; neither establishes an earliest historical date.

Raw grain flour can carry harmful bacteria.
Hazard sourceRaw eggs can carry Salmonella before baking.
Hazard sourceDo not taste raw dough. Keep flour away from ready-to-eat foods and clean hands, utensils and surfaces after handling.
Control sourceDo not taste raw dough. Keep raw eggs and dough separate from ready-to-eat foods. Wash hands, bowls, utensils and surfaces after handling them; bake according to the recipe.
Control sourceThe 190°F centre reading is the recipe's baking cue, not an independently validated microbiological critical limit. Brown colour and hollow sound do not prove safety. The publisher suggests wrapping after complete cooling and up to one week at room temperature; that is household quality advice, not a validated shelf-life guarantee.
Regional bread association, not a claim that this American household formula originated there.
