EVERYDAY BAGUETTE
Make your own crunchy baguette at home. 
This is how to make a crunchy French baguette at home, using basic supermarket ingredients and the simplest technique.
INGREDIENTS
For a standard baguette or a chunkier demi baguette (half a baguette)
250 g (7 oz) white bread flour
175 g (6.2 oz) water (see formula in the video for temperature)
5 g (0.2 oz) of sea salt
3 g of instant dry yeast
Cooking time: 20 to 25 minutes depending on how well cooked you want the bread to be.
Cooking method: Temperature 255°C (about 490°F) with steam. To create steam, place a container with water at the bottom of your oven and let it heat up until lots of steam is released.
NOTES
Hydration level: the amount of water used for the flour is typically 70 percent of the flour weight. But keep in mind that certain types of flour, like a stoneground flour for instance, will absorb more water so you may have to use a bit more water than the standard measure for your dough (a ratio of 75 percent of the flour weight should do).
What makes a good Baguette? It's the quality of the ingredients, water (mineral or spring water yields best results). salt (good quality natural salt or sea salt) and use fresh bakers’ yeast or industry grade dry yeast.
Ensure the correct dough temperature after kneading. This is calculated using what is called the base temperature reference. In French this is called the TB (temperature de base).
Mastering the dough temperature: the base temperature is a value in degrees centigrade that is used to calculate the temperature which your water needs to be when making a bread dough for a baguette. This calculation allows you to get an ideal temperature after kneading which sits between 23-25°C (between 73-77°F).
TB Formula (to calculate temperature of water added to knead the dough). The Base Temperature number is 65 °C (149°F). Take the room temperature and the temperature of the flour. Then add the two together and deduct the total of the two from 65°C (149°F). The resulting number is the temperature in degrees centigrade for the water.
PROCEDURE
Place the flour in the bowl of a Kitchen Aid or any other food processor with a dough hook.
Dissolve the salt in the water and then ensure that the temperature of the water corresponds to the result obtained by using the TB formula.
Add the water into the bowl with the flour.
Using the dough hook of the stand mixer or kneading machine, mix the flour and water on speed No 2 (low speed) until all the water has been absorbed by the flour. It will take 2-3 minutes. If necessary, tap the sides of the bowl or use a rubber spatula to get all of the flour into the mix.
Remove the hook (after scraping off all of the dough), cover the bowl with loose plastic or parchment (baking) paper and leave the dough to rest at room temperature for 45 minutes.
Add the yeast, replace the hook and knead the dough for 8 minutes on speed No 2 and then accelerate the speed toward the end for 1 minute then stop.
Again remove the hook and scrape off all of the dough – the temperature should be between 23 and 25 degrees Celsius (73 to 77 degrees Fahrenheit).
Sprinkle a clean bowl with flour and place the dough in and cover the bowl with a plastic wrap or a humid tea towel and leave to rest for 1 hour. The dough will rise a little.
After an hour scrape the dough from the bowl onto a floured bench, shape into a rough rectangle shape and fold each of the 4 edges towards the centre to make a sort of ball turn the dough around so you have the round shape facing up then place back into the floured bowl.
Cover the bowl again and leave it to rest for 2 hours at room temperature and then place the bowl into the fridge to allow the dough to ferment overnight.
The next day, remove the bowl from the fridge and allow it to stand at room temperature for one hour – sprinkle some flour over the top of the dough.
Scrape the dough onto a floured bench – the dough must not stick to the surface.
Remove the “gas” from the dough by forming it into a rectangle and pressing down on it a little bit
Pre-shape the baguette by folding one half of the long side of the rectangle back onto the other half, fold back each of the four edges towards the centre (see video)to make a sort of long round shape bread roll.
Place the pre shaped dough on a sheet of parchment (baking) paper and allow to rest at room temperature for 20-30 minutes.
Pre-heat a non-fan-forced oven to 255 degrees C. If the oven has a steam function, use it. If not, place an oven proof dish or container on the bottom of the oven and just before baking, when that temperature is reached, add water to the dish. place your baking stone or metal baking sheet inside the oven during that time too.
