The invention comprises a process and a product which, by using conventional and basic equipment and without requiring any particular system or equipment for defrosting and fermentation, achieves an optimum-quality product in relation to which the consumer cannot determine whether it is fresh or the result of a defrosting process. Thus, a bread dough is achieved which is suitable for elaborating medialunas, vigilantes [both are croissant-type products], and all types of bread, of different shapes and sizes, and the post-baking quality of which is highly advantageous in terms of flavor, texture, aspect and volume, these characteristics not being altered after defrosting. The type of oven for baking the dough can be: brick-built, rotating, tunnel, convection or pastry ovens of any dimensions, and no special installations for defrosting and fermentation are required.
