It used to be that the team would unlock all of the previous recipes when relisting appliances for a goal but that changed a while back. Now, only recipes unlocked via the current goal are opened when appliances are relisted. So that means:
Completing the current goal will only unlock the three recipes that are shown in the first post: Squash Toasties, Cheesy Corn Fritters, Ricotta Beets.
The three recipes from the Pub Stove's original release (Cheese Soup, Bangers, Beans n Eggs) should be unlocked to everyone as they were not goal-related.
The three recipes that were released back in a 5 Day Goal on March 12 of this year (Bangers and Mash, Pub beef Egg Roll, Corned Beef) will likely remain locked to those who did not participate in said goal.
