By creating a Key ;-) Seriously, the algorithm preferences are stored in the self-signature of a user ID (You can review them by running gpg --list-packets on a public key file or using the pref command in the --edit-key function). I don´t know, whether algrithm preferences are possible at all with RSA keys/v3 sigs. Currently the preferences 10/4/3 (Twofish, Blowfish, Cast5) are hard-wired into the GnuPG key creation process. You´d have to go source-diving to change them (g10/keygen.c, IIRC). Apparently, editing functionality is on the wish list for version 1.1. See also: HTH.
