- How do I scale a Carbonara recipe from 4 to 20 people?
- Multiply all ingredients by 5 (20 ÷ 4). For Carbonara: 400 g spaghetti → 2,000 g; 5 egg yolks → 25 egg yolks (use 20 yolks + 2 whole eggs for large batches); 125 g guanciale → 625 g; 75 g Pecorino Romano → 375 g. Note that technique changes at scale — finish the sauce in batches to prevent scrambling.
- Do I scale every ingredient linearly?
- Almost all pasta ingredients scale linearly. The main exceptions are: salt and strong spices (scale to 80–90% to avoid over-seasoning); aromatics like garlic and chilli (scale to 70–80% — they intensify in large pots); and pasta cooking water for emulsification (adjust by feel, not formula).
- What is the base recipe for Pasta all'Amatriciana (4 people)?
- Classic Amatriciana for 4: 320 g bucatini or rigatoni, 150 g guanciale, 400 g San Marzano tomatoes (peeled), 60 g Pecorino Romano (grated), 1 dried chilli (peperoncino), 100 ml dry white wine, black pepper. No onion — the traditional recipe from Amatrice uses only guanciale, tomato, pecorino, and peperoncino.
- How should I scale eggs for Carbonara at large quantities?
- For 1–4 portions: use only yolks (1 yolk per person). For 5–20 portions: use a mix of whole eggs and yolks (1 whole egg + 1 yolk per 2 people). For 20+ portions: use 1 whole egg per 2 people, or switch to pasteurised egg product for food safety at scale. The yolk-to-white ratio affects creaminess and setting point.
- What is the baker's percentage approach for pasta recipes?
- Baker's percentage expresses every ingredient as a percentage of the base ingredient weight (pasta). Example for Carbonara: pasta = 100%, guanciale = 31%, egg yolks = 19%, Pecorino = 19%. This makes scaling trivial: multiply pasta weight by each percentage. It also makes recipe documentation consistent across different batch sizes.
- How do I adjust cooking water and salt when scaling a recipe?
- Water and salt scale with pasta weight using the 10-10-100 rule: 1 litre water + 10 g salt per 100 g pasta. For 2 kg pasta, use 20 litres water and 200 g salt. At large scale, a professional pasta cooker (cuocipasta) with continuous water circulation is more practical than multiple large pots.
