Sims Mobile: Cooking items collection

I'm not 100% sure but I think those unlock with the 3th Sim that does the hobby. 

Those three items have a level limit.  You have to be high enough level at the time you complete the cooking hobby.  I can't remember if the level is 32, 33 or 35.  

Thank you everyone! i will try and level up more to get them, then.

And don't retire your Cooking Hobby SIM until you have everything, otherwise it will lock the items until another SIM levels up in the hobby...that's what happened to me. I didn't have enough $ to buy the the items and I retired my SIM. Now I have to use another SIM and start all over again. Some of the items aren't available until level 30 something either. Bummer.
