Carefully add most of the boiling water (reserving about 2 -3 teaspoons) to the flour while stirring to combine. Once the mixture begins to come together, tip out onto a work surface (lightly floured if necessary), and knead until the dough starts to come together. The dough will feel a little sticky at first, but should come together quite quickly. If it still feels sticky, add a teaspoon or two of flour and continue to knead till smooth and not sticky. Conversely, if the dough feels too dry, add the remaining water by the teaspoon until it comes together.
