online recipes, we have left the books on the shelf, thus preventing their pages from getting dirty while we prepare food in the kitchen. On the contrary, we now have mobile devices that we have to manipulate to see the complete recipe while our hands are full of food scraps. We do not know what is worse, dirtying the books or the tablets and mobiles. What we do know is that cooking recipe apps are here to stay. Now the job is ours to choose the application that best suits our culinary needs.
