so i put egg yolks and water in a cup
warmed up some butter and put that in the cup
this is where it went “wrong”.
added hot cocoa (cocoa and water boiled) & sweet’ner, as well as some cream, instead of mustard
it turned out relatively runny like a hot chocolate should
it had an unpleasantly buttery flavor but was relatively palatable
ps: is butter an acceptable fat to mayonnaise with?
Ewwww. Did you eat it though? I probably would have tried it.
…To boldly go where no one has gone before…
No butter in mayo! Avocado, coconut, olive, bacon grease. Coconut oil and Bacon grease both require some Avocado or Olive oil so you don’t end up with solidified mayo when refrigerated. 
Wouldn’t the same precautions to bacon grease apply if you did make butter mayonnaise?
What’s the problem with butter mayo anyway?
I have like 2.25kg of butter that I can use no other way (because I don’t like it melted over meat - too greasy) unless I just make a fsckoff obscene amount of omelettes, fried pork and beef chops, just a lot of fried food that’ll give me trouble in the form of hypersatiety from my duodenum (trouble that I call gallbladder trouble because it’s linked with a large amount of fat).
Apparently, an egg yolk can soak up up to a litre of oil without splitting. I’d still stick to no more than 454g (one entire block of butter) per yolk but to each their own.
Come on, David! Be bold and go where no one has gone before. When I finally get around to it I intend to try both butter mayo and lard mayo.
Freeze it for using over time. That’s what I do. I get lots of butter when I get deals like $2 lb. and freeze it.
It’s just the juxtaposition of “relatively” with “okay”—it wasn’t absolutely okay, just relatively okay–especially when I was expecting “vile,” lol!
(You may have noticed I have an odd sense of humour.)
I need me some solidified mayo to just eat with a spoon!
Mind you I’ve been known to have a spoonful of mayo on the rare occasion I need something to tide me over…
I sometimes think of artichokes as a mayo delivery system. Get some mayo with a little fresh lemon juice, some pink salt… and dip away with the artichoke.
No one has to know that I eat the leftover mayo with a spoon (cause I would never just lick it out of the bowl!).
Waste not… want not…
This would be hollandaise! A little more fiddly but jolly nice!
Cocoa? …mmmm …novel I suppose
@Halo Shocking! I should have figured someone had already done it, the internet reveals the fact that whatever idea you think is original has been done already.
Relatively okay describes the chocolate omelette I ended up with when I was trying to guess at a mug cake. We don’t waste food around here. 
What kind of crazy person are you??!? 
Everyone knows that artichokes were made for lemon butter!
(actually, now that I think of it . . . )
