What is Lamination?

Lamination starts with a lean dough — flour, water, salt, yeast. You're aiming for a dough that's strong enough to hold butter without tearing, but not so rich that the butter melts into it. A typical croissant dough uses 500g bread flour, 250ml water, 10g salt, and 7g instant yeast. This dough costs you about $1.85 in ingredients. Now you wrap 250g of butter (about $2.10) into that dough and fold it six times. Each fold doubles the number of layers. After six folds, you have 2^6 = 64 layers of dough and butter alternating. Some bakers do seven folds to reach 128 layers, which gives you a lighter, more dramatic rise — but it takes 30 minutes longer and uses 50g more butter, adding $0.42 to your cost per batch. Why does this matter to your bottom line? A 50g croissant (unbaked) bakes down to about 38g after water loss. If you're selling croissants at $4.50 each and making 32 croissants per batch, your revenue is $144. Your ingredient cost is $1.85 (dough) + $2.10 (butter) = $3.95 per batch of 32, or $0.123 per croissant in ingredients. But here's the catch: if your lamination is uneven — some folds too tight, some too loose — your oven spring is inconsistent. You get 28 sellable croissants instead of 32. Your per-unit cost jumps to $0.141, and you've lost $0.54 in revenue per batch, or $10.80 per week if you bake 20 batches. Lamination also controls your bench time and labor cost. A six-fold lamination takes 2 hours from mixing to final fold, with 20 minutes of active folding and 100 minutes of rest between folds. A seven-fold lamination takes 2.5 hours. If you pay yourself $18/hour, that's an extra $9 in labor per batch — or $0.28 per croissant. Add that to your ingredient cost and your croissant now costs $0.42 in labor and ingredients. At a $4.50 selling price, your food and labor cost is 9.3%, leaving 90.7% for overhead and profit. The number of folds also affects your dough loss. Every time you fold, you're handling the dough, and small pieces stick to the bench or your hands. A six-fold lamination typically loses 20-30g of dough per batch (about 3-5% loss). A seven-fold loses 35-45g (5-7% loss). Over a year, if you make 1,000 batches, that's 20-45kg of dough you're giving away — at $0.12/g, that's $2,400 to $5,400 in lost revenue.
