A brand new banneton is effectively ‘green’ and it needs conditioning before it is ready to use. I think that Bannetons work best with a thin build-up of moisture and flour which needs to be worked into all its nooks and crannies. The idea is to put a permanent layer of flour onto the banneton so that it adheres to the fibres. On… Read More about Banneton
To increase hydration and get a more open crumb it is best to add more water just a little bit at a time. The technical term for this is what the French call called Bassinage. We don’t have an English direct translation for, but it means water that is worked into the dough in small increments during the bulk fermentation. It is a very traditional technique, but what is really important to remember is that the ” eau de bassinage” ( the water) is removed from the total water in the… Read More about Bassinage
A batard is a loaf shaped like a baguette, but much wider and shorter. It has tapered ends and is slashed diagonally and baked using exactly the same method as the baguette.

Inflammation is your body’s way of responding to and defending itself against injuries, infections and even, in some cases, food that your immune system recognises as a threat. When your immune system detects the presence of a microorganism or injury, it responds by sending protective white blood cells to the site in your body it feels is under threat. This promotes repair. The inflammation itself is a result of fluid and white blood cells in the surrounding tissues, which cause swelling while supporting the healing process. In some cases, inflammation… Read More about Inflammation
