Making baguettes at home might seem to be an impossible thing, but it really isn't. There's a lot of steps involved in the fermenting/proving of the dough, so this recipe is basically short bursts of activity interspersed with longish periods of waiting. But a homemade baguette, fresh from the oven, is a thing of wonder!
Now we do the final formation of the baguettes. Traditionally, French bakers would use a thing called a couche to support the baguettes while they rise. This is simply a square of heavy duty linen, but don't worry if you haven't got one - a clean tea towel or pillow case will do just as well. Generously coat your 'couche' with flour. Arrange it so that the far edge is standing vertically for about 5 cm (2 inches) up against a wall, or a cereal box or anything else with a vertical edge. Take a piece of dough, place it on a floured surface, sprinkle more flour on top and on your hands. Use your fingertips to spread the dough out into a long rectangle (basically the length you want your baguette to be). Lift up the edge furthest from you, and roll the dough towards you. Use the heel of your thumb to seal the edge closest to you. Roll the baguette once or twice to smooth it, then lift it onto the couche, making sure it fits snugly up against the far edge. Grab the two edges of the fabric about 7.5 cm (3 inches) away from the baguette and lift it up to form a kind of channel that holds the baguette. Repeat with the second piece of dough, then cover the baguettes with a clean tea towel and leave to prove for 30 minutes.
At some point during this proving, you need to turn your oven on to preheat to 190° C (374° F) fan, or 210° C (410° F) conventional, gas 7. Place a roasting tray with boiling water in it to generate steam.
