Hi djo,
I am having exactly the same idea and problem. My wife and I use a cooking blog on a mobile phone and it is very easy to send a link with a particular recipe to a given email address with the link in the body of the email. Based on that my solution (not tested yet) is the following.

Setup an email client and a parser on your Raspberry so that the url is taken out of the email and written down to a separate file. Example here.

Use one of these modules iFrame or iFrame Reload to load the contents of a html file. The difficulty here is that the file is not on the Internet but it’s a local file.

The parser from 1 can construct the local file in such a way that it contains another iFrame pointing out at our url with the recipe.

We need a way to get rid of the recipe from the screen after, say, an hour. This is something to be worked out. Maybe the second module can handle that. Or any other way - voice, another mail, etc.?

This is my rough thinking. I will be testing it quite soon. Let you know about the results.
