So you “offered “ to cook as your wedding gift but it has to be absolutely only on your terms ? What’s the point of a gift for THIER wedding if you know it’s something they both can’t or wont enjoy ? Sounds like you really didn’t discuss what you were going to cook you just decided and if they didn’t like it in its entirety you threw a fit . Either it’s a gift to show them love or it’s for your own personal gratification.
