There's lots of things. Making chocolate mousse is seems to be a dark art to lots of people I know. One person was fascinated by the whipping of heavy cream in to whipped cream as if some voodoo power was being invoked. To then it only came in cans or tubs of fake cool whip. Lastly was when I had some dinner guests and made a banana pudding from scratch before their eyes. It was as if I summoned a demon to aid me in having a hot fresh dessert.
Honestly, knowing how to google things constantly seems like a mystery to people.<p>I often get people saying "how do you know all these things?" and just have to reply "I'm really good at googling."
