Trivia
At the time of the large estates, after the harvest and harvest of the grain, the fields were set on fire in order to "clean" them in view of the next sowing. It happened that some grains of wheat remained on the ground that escaped the harvest, but burned by the fire. The sharecroppers collected them and made a flour to take home. This is how burnt wheat flour was born.
