Yes, that was the case. But I really think they should highlight this trait when trying to prepare a meal, I would never have thought about that.

Do they have the tool tip feature where you hover over the thing that is grayed out and it tells you why you can't make it, similar to handiness upgrades? I don't have this pack so I don't know, but that would be nice!

I have greyed out baking recipes currently but I don't have Cottage living and there are no lot challenges on the house. The lot didn't have any traits or challenges when I downloaded it from the gallery. My sim cant bake any of the recipes that I don't have all the ingredients for. I wanted to make quiche but don't have the spinach. My sim has level 6 baking skill. Quiche requires level 5.

I do have mods. Not sure if this is intended gameplay.

I don't usually play bakers and my sims tend not to bake unless its a birthday cake. My current sim is a baker. The non-baking recipes seem unaffected. My sim has a big garden so I have a lot of ingredients. Because of this I didn't notice this limitation.

@CrystalWB For Cooking and Gourmet Cooking you will see a 'use fresh ingredients' option box that you can tick or untick to let your Sim cook or not cook a meal that they have/have not got the ingredients for. 

However, for Baking your Sim will need to have certain (listed) ingredients in order to bake certain items. There is no box for a 'use fresh ingredients' option box that you can tick or untick to let your Sim bake a meal that they have not got certain listed ingredients for. For instance:

If I want my Sim to make a Spinach and Onion Quiche, but she does not have a spinach or and an onion, she has no option available to make that quiche:

However, if I have her harvest a spinach and an onion from her plants, she does have the option available to make that quiche:

This is not due to Mods/CC [I do not have any nor have I ever had any in my game, and this lot and save are from way before Cottage Living (no simple living trait)]. It has been like this for Baking as long as I remember. I also think it's odd. Perhaps it's for the purpose of making Baking 'extra special'?
