Alors ça pour moi c'est faux. Moi qui n'aime pas les gros corniciones même en abaissant fortement sur le bord de mon paton ça ne change rien.

Il y a pourtant des différences suivant le type d'abaisse utilisée, teste par toi même lors de ta prochaine session.

Bonjour, Serait-il possible de mettre les images manquants sur le FP (première page du Topic ) ?
les liens sont obsolètes . les images sont disponibles dans le cache Google .

Je vais y penser, j'ai encore les photos sur le HD.

Hardness
Various minerals can be found in water. Two of them—calcium and magnesium—play a major role in water hardness and also in dough-making. The type and amount of these minerals varies with the locale.
Medium-hard water—that is, water with 50 to 100 ppm (parts per million) of carbonates—is the best for baking. It contains the right amount of mineral salts—mostly of calcium and magnesium—which strengthen gluten and also, to some extent, serve as yeast nutrients.
Soft water (less than 50 ppm carbonates) has a shortage of those salts, which tends to result in a soft, sticky dough because there’s less gluten-tightening effect from minerals. To counteract stickiness, reduce the water portion by about 2 percent. It can also help to increase the salt portion up to 2.5 percent of flour weight. On the baked pizza, the soft water tends to produce a crust texture and color that’s less than optimum.
Hard water (over 100 ppm carbonates) has too much of the salts. This toughens gluten excessively, which retards the fermentation or rise of dough. To counteract that, increase the yeast level and, if it’s used, adjust the amount of yeast food. Also, adding malt or malted flour might help.
PH is important in dough-making because it affects chemical and biological reactions. Most notably, it affects the rate of amylase enzyme performance (conversion of starch to sugar) and, as a result, the rate of fermentation. The optimum pH for starch conversion and fermentation and, hence, for pizza dough, is about five, or slightly acidic. This pH level is best achieved by using water with pH6.5 to 8.0, with pH7.0 being the optimum.

Water is an ingredient of considerable importance in bread dough. Although it is easy to overlook -- after all, turn on the tap and it is there -- it is
beneficial to be aware of the effects water has in our baking. The most important attributes are the following:
• It is in the presence of water that gluten forms.
• Water serves as a solvent and dispersing agent (for salt, sugar, and yeast).
• Water is necessary for yeast fermentation and reproduction; softer doughs will ferment more quickly than dry doughs;
• Water is responsible for the consistency of bread dough.
• The temperature of water can be varied in order to obtain dough of the correct temperature.
WATER HARDNESS
The degree of hardness is and indication of the amount of calcium and magnesium ions in water, expressed in parts per million (ppm). Soft water
has less than 50 ppm, while hard water has over 200 ppm. Generally, water of medium hardness, with about 100 to 150 ppm of minerals is best
suited to bread baking. The minerals in water provide food for the yeast, and therefore can benefit fermentation. However, if the water is excessively
hard, there will be a tightening effect on the gluten, as well as a decrease in the fermentation rate (the minerals make water absorption more difficult
for the proteins in the flour). On the other hand, if water is excessively soft, the lack of minerals will result in a dough that is sticky and slack.
Generally speaking, most water is not extreme in either direction, and if water is potable, it is suitable for bread baking.
In the creation of a sourdough or levain culture, there is another consideration. If the water used is highly chlorinated, the chlorine can have a nega-
tive impact on the culture. In this case, simply leave a bucket or jar of water out overnight, uncovered. By the next day, most all the chlorine will
have dissipated.
WATER AND pH
The degree of acidity, expressed as pH (potential hydrogen), also has an effect on fermentation. Hard water is more alkaline than soft water, and can
decrease the activity of yeast. Water that is slightly acid (pH a little below 7) is preferred for bread baking.

Autre chose que j'ai constaté avec l'eau à 22°f: je n'ai plus d'effet caoutchouc quand la pizza refroidie, chose que j'avais systématiquement avec la Divella Pizza par exemple.

Très intéressant ça !
