Rough Puff Pastry Calculator

Full puff pastry involves encasing a block of butter in dough and performing precise lamination folds over several hours with resting between each turn. Rough puff is a quicker method where cold butter is cut into cubes and mixed directly into the flour, then the dough is folded and rolled several times. Rough puff produces fewer layers (typically 80-250 vs 729 for full puff) but is much faster and still gives excellent lift and flakiness.

Rough puff typically requires 4-5 single folds with a rest in the fridge between each pair of folds. Four folds produce 81 layers, which is more than enough for excellent flakiness. Do not over-fold or the butter will become too evenly distributed and you will lose the layering effect.

A small amount of acid (lemon juice or white wine vinegar) helps relax the gluten in the flour, making the dough easier to roll and less prone to shrinking. It also slightly inhibits gluten development, resulting in a more tender pastry. About ¾ to 1 teaspoon (roughly 4–5 ml) per 200g of flour is plenty — this calculator defaults to 2% of the flour weight, which works out at about 4 ml per 200g.

Yes, rough puff freezes brilliantly. Wrap tightly in cling film after the final fold and freeze for up to 3 months. Defrost overnight in the fridge before rolling. You can also freeze rolled pastry sheets between layers of baking paper. Frozen rough puff often performs better than fresh because the butter is extra cold.

Cut the butter into roughly 1-2cm cubes and keep them cold. The visible chunks of butter are what create the flaky layers during baking. If the butter is too small, it will blend into the flour and you will end up with something closer to shortcrust. You should still see streaks of butter in the dough after folding — this is correct.
