Iced Puff Pastry

Name: Iced Puff Pastry
Ingredients: 1 pound Superfine wheat flour (or all-purpose flour) (Originally '1 ratal superfine flour'.); 1 teaspoon Salt (Quantity estimated (originally 'finely ground salt').); 1 pound Butter (cold and firm) (Originally '1 ratal butter'. Ensure water is pressed out.); 4 cups Ice (Crushed. Used for making ice water and for the cooling tray.); 1 cup Water (Quantity estimated. Must be ice-cold (melted from ice).); 1 yolk Egg yolk (For glazing (optional).)

This historical recipe utilizes a unique cooling technique where the dough rests on crushed ice between turns, ensuring the butter remains perfectly solid for maximum flakiness. It yields a classic, high-rise puff pastry with distinct, airy layers and a rich, buttery flavor superior to standard methods. Ideal for savory pies, vol-au-vents, or sweet tarts, this dough creates a delicate, golden-brown crust that shatters beautifully upon biting.

Ingredients

1 pound Superfine wheat flour (or all-purpose flour) (Originally '1 ratal superfine flour'.)
1 teaspoon Salt (Quantity estimated (originally 'finely ground salt').)
1 pound Butter (cold and firm) (Originally '1 ratal butter'. Ensure water is pressed out.)
4 cups Ice (Crushed. Used for making ice water and for the cooling tray.)
1 cup Water (Quantity estimated. Must be ice-cold (melted from ice).)
1 yolk Egg yolk (For glazing (optional).)

Instructions

1Take some of the ice, crush it, and allow it to melt to create very cold ice water.
2Sift the flour into a large plate or bowl and mix in the finely ground salt. Take the pound of butter (ensure it is free of water and slightly firm) and divide it into 6 equal parts. Take one of these parts and mix it into the flour with a light hand. Gradually add just enough ice water to bind the flour into a dough without kneading it heavily. Form it into a ball.
3Dust a pasteboard (or clean work surface) with flour. Place the dough ball on it and roll it out into a rectangular sheet approximately 6 inches wide and 12 inches long, ensuring even thickness throughout. Take the second part of the butter and spread it evenly over the dough. Dust lightly with flour. Fold the dough into layers (typically in thirds or five layers as described) while keeping the 6-inch width.
4Prepare a cooling station: Place four large pieces of ice of equal height close together in a tray. Place the folded dough onto a shallow enamel plate, then set this plate on top of the ice in the tray. Let the dough rest and chill for 10 minutes.
5Lift the dough from the ice plate. Dust the board with flour again. Roll out the dough as before, spread the next part of butter, fold, and return it to the ice plate for another 10 minutes. Repeat this process until all remaining parts of the butter have been used.
6After the final chill, lift the dough and roll it out to the desired size for a pie or other pastry. If using for a pie, brush the top with beaten egg yolk thinned with a little water. You can use trimmings to decorate the center. Bake in a hot oven (approx 400°F/200°C) until puffed and golden brown.
