The plane question- I’m particularly wondering about the no-liquids-over-3oz rule- for instance, if whip cream starts out as a liquid but then gets stabilized, whipped, rolled in a cake and frozen, is it subject to that rule? I’m going to go call the airline, but I would be interested in anyone’s experience bringing cakes on planes since that rule went into effect.
Editing to say, I found this on the TSA website: “You can bring pies and cakes through the security checkpoint, but please be advised that they are subject to additional screening.”
I also saw a travel blog that said additional screening could mean the security officer needing to slice or otherwise open the cake to check its contents. If I try it, I’m definitely going to bring plastic spoons for them to use, if needed, and probably some of those white gloves to keep the cake clean. Then maybe a 3 oz jar of ganache to fix/touch up the cake once I get there. It does sound like frosting/paste/cream type textures are subject to the 3 oz rule when packaged separately.
Editing again… more reading… there are some people who have successfully brought frosted cakes through security, while others have had them confiscated, due to the frosting and the 3 oz rule (or maybe the agents were just hungry and the cakes looked good!). I did come across more examples of people who had done it successfully than ones who had had their cakes confiscated.
