This tool tells Google that it’s the same site, just a new domain. Unfortunately for me, they don’t recognise “.re.it” as a root level domain, so was unable to make use of this feature.

Instead I have to rely on a 301 redirect. If, like me, you’re using cPanel and have the old domain as a parked domain it will not issue a 301 header, however you can override this in your .htaccess file.

RewriteEngine On
RewriteCond %{HTTP_HOST} ^(www.)?sha.re.it$
RewriteRule ^.* "http://36flavours.com/$0" [R=301,L]

Here we check to see if the domain is sha.re.it or www.sha.re.it and if so, redirect to http://36flavours.com with the 301 header.
