A cooking recipe portal project is a web application that allows users to view, search, and submit recipes. It typically includes the following features:

1. Recipe Listing: Users can view a list of all available recipes, sorted by categories such as cuisine, meal type, and ingredient.
2. Recipe Detail: Users can view detailed information about a recipe, including ingredients, preparation instructions, and user-submitted ratings and comments.
3. Search: Users can search for recipes by keyword, ingredient, or category.
4. User Accounts: Users can create an account, log in, and submit their own recipes. They can also save recipes to their personal recipe box.
5. Recipe Submission: Users can submit new recipes, including a title, description, ingredients, instructions, and images. The recipes will be reviewed by an administrator before being published.
6. User Profile: Users can view and edit their personal information, including their name, email, and password.
7. Administrator Dashboard: Administrators can view and manage all submitted recipes, approve or reject them, and manage user accounts.
8. Responsive Design: The website should be responsive and accessible on all devices, including desktops, laptops, tablets, and smartphones.
9. Social Media Integration: Users can share recipes on social media platforms, such as Facebook, Twitter, and Pinterest.
10. User Interaction: Users can rate, review and make comments on recipes, and also interact with other users.

To create a cooking recipe portal in ASP.NET, you would need to use a combination of technologies such as HTML, CSS, JavaScript, and C#. You could use a framework such as ASP.NET MVC (Model-View-Controller) to structure your project and handle the routing of user requests. You would also need to use a database to store information about recipes, such as the ingredients, instructions, and user-submitted ratings and comments.

Here is a general overview of the steps you would need to take to create a cooking recipe portal in ASP.NET:

1. Create a new ASP.NET MVC project in Visual Studio.
2. Design the layout and style of your website using HTML, CSS, and JavaScript.
3. Create models for your recipes, users, and other data that you will be storing in the database.
4. Use Entity Framework (ORM) to connect to the database and perform CRUD operations on your data.
5. Implement the functionality for displaying recipes, allowing users to submit new recipes, and allowing users to rate and comment on existing recipes.
6. Test and debug your application, and make any necessary adjustments.
7. Deploy your application to a web server for it to be accessible to users.

This is a high-level overview and there are many details involved in each step. You might consider starting with a pre-existing recipe template or looking up online tutorials for more information on specific technologies you may not be familiar with.
