My husband said I can substitute mayo for the shortening in my buttercream. I know you can use it for substituting shortening in other things....but icing????

I just wanted every one's input, if you've tried it or not. I'm to scared too!! I don't care for mayo in the first place and it just sounds gross.

I'm sorry, but that just made me throw up in my mouth a little. I would NOT be willing to test that theory out myself... ick.

That would also make it have to be refrigerated!

Well, tell your husband to make up a batch for you so you can try it out. And while he's at it, tell him to make a cake too.

Even if it did work that would taste so nasty! I would stick to the shortening!

Isn't mayo made of raw eggs???? Fine on a sandwich, but leave it out of my icing!

Husbands............ What will they think of next?..........Whipped cream in the bedroom?

Yeah...throw up. In. Mouth. Almost. Ugggggh!

I've heard of mayo IN cakes (I think Hellmann's used to have it on the label--maybe it still does!), but not on them. I think mayo in the icing would make it salty and gross.

What was he thinking? It must be a guy thing. lol How funny. Maybe in cakes but not icing honey.

It would be all sloopy and goopy wouldn't it? Shortening and butter are firm. I also have heard of it in cakes, but I don't think it would work for buttercream. Who knows though...why dont you try it and let us know how it turns out!

I don't use mayo in ANYTHING. I use something else for potato salad, deviled eggs, chicken salad, etc.

So, yeah, this sounded totally gross to me.

What's his logic? They're both WHITE?

Merissa is right.......it is much too soft/sloppy. It would never make icing. You need *solid* shortening &/or butter.
