Rewrite if install your plagin?

I’m afraid we are not able to import those recipes automatically. How many recipes are we talking about?

Technically it would be possible to code your own Custom Recipe Importer, but it would require some development and I do not have time for freelance work myself.

Alternatively the Import recipe from text feature could help speed things up when moving recipes over manually.

When installing your plugin, it adds field to the posts? that will need to be manually filled out?

You add recipes as a block/shortcode to your posts:
