Gluten-free flaky pastry

Instructions

1. Combine the tapioca starch, potato starch, pea flour, brown rice flour, sorghum flour, xanthan gum and salt in the bowl of a stand mixer fitted with the dough hook. Scatter over the butter cubes. Mix on medium speed until the mixture looks like breadcrumbs. With the mixer running, add the water and mix to bring it all together into a firm dough with the texture of playdough. It should have a slight stickiness; if it feels too dry, add more water, 1 tbsp at a time, incorporating it fully between additions.
2. Tip the dough onto a lightly floured kitchen bench and knead it for 3–4 minutes, then shape it into a rectangle roughly measuring 18 × 20 cm (7 × 8 in). Cover and refrigerate the dough for 2 hours, or overnight.
3. Meanwhile, prepare the butter for laminating. Place the butter block between two sheets of baking paper and use a rolling pin to roll it into a rectangle roughly measuring 18 × 20 cm (7 × 8 in). Put the butter in the fridge, between the sheets of baking paper, and refrigerate for 2 hours, or overnight
4. Remove the dough and rolled-out butter from the fridge 15 minutes before you laminate the pastry. You want the butter to be malleable but not too soft.
5. Lightly dust your kitchen bench with rice flour. Lay the dough rectangle on the bench with one short side parallel with the edge of the bench. Roll the dough away from you to form a rectangle measuring 20 x 40 cm (8 x 15¾ in), still with the short side closest to you.
6. Place the butter block in the middle of the dough. with the 20 cm (8 in) side of the butter parallel with the bench. Fold both free short sides of the dough over the top of the butter so they meet in the middle, encasing the butter. Lightly pinch the ends together to seal (the seam should run parallel with the bench).
7. Rotate the dough block 90 degrees so the seam is now perpendicular to the bench. Using your rolling pin, gently press or stamp along the length of the dough to make it more malleable (you can do this at any stage in the process to make the dough easier to work with). Roll the dough away from you to form a 20 x 40 cm (8 x 15¾ in) rectangle, again with one short side parallel with the bench. Starting from the side closest to you, fold the bottom third of the dough into the middle, then the top third over the top of that, as if folding a letter. Rotate the dough 90 degrees anticlockwise, placing the open seam to the right. Repeat this step three more times, rotating the dough 90 degrees between each fold.
8. As mentioned, there’s no need to rest the dough between folds; there is no gluten in the flour, so the dough will not shrink. However, you do need to be careful that the butter doesn’t get too soft, especially in a warm kitchen. If it starts to feel too soft, put it in the fridge for 30 minutes after the second fold before proceeding.
9. Once all four folds are done, wrap your pastry and chill for at least 1 hour before use. Leave the pastry at room temperature for 15 minutes before you use it, to soften slightly. Roll the pastry between two sheets of baking paper to the required shape and thickness, then wrap and return it to the fridge for 1 hour before using. The pastry will keep 5 days in the fridge, a up to 3 months in the freezer.
