On every recipe's page the logged on user will find the Mark for cooking button in the right side. By clicking on it a calendar will appear, and clicking on the days you can select the day of cooking which will be marked with red. When the time of cooking comes, the selected recipe will appear on the Home page in the Recipes planned for today zone (above the Recipe of the day). You can list the recipes marked for cooking under the Settings menu in the Cooked recipes and in I will cook tabs.
