you can overwrite them by just picking a new recipe wit the same special touch but I don't think there's a way to remove them.
Its a little wonky but it mostly works. If the item im replacing is the same recipe/name/perk and its less than like, half of the way down the list, it will keep the old one. If its a different recipe but the same name/perk then it will add the new one to the top of the list. I haven't tried with different names for the recipes.
Edit: If yours is not replacing the old entry with the new one that has a different name or dish used, but he same perk, then no, I haven't had that issue
Finally got to test this again and it always worked, except when the recipe I want to replace something with is Grilled Fish. The game doesn't seem to like the Grilled Fish as family recipe replacement. 😅
