From the cookbook Cajun-Creole Cooking by Terry Thompson a chef and food critic who lived all her life in New Orleans. No need for misters, steam, clay bricks or complicated procedures. This recipe was developed for the food processor.
Her note: A scientific discovery made by my good friend, Shirley Corriher, led to the addition of flavored vinegar to the French bread recipe. When testing breads prepared according to the age-old, long, slow-rising French method, it was discovered that the dough became acidic during extended and numerous risings. Her conclusion was simply to add acid at the beginning of the bread-making process. The resulting loaves had both the aroma and taste of the slightly soured and yeasty breads of Europe, without the long rising! Try this method with your favorite bread recipe, using as your guide one teaspoon of fruit-flavored vinegar for every three cups of flour. Don't be tempted to add more vinegar; excess acid can destroy the gluten in the flour. Please follow directions precisely.
