In all the years of writing this blog, I’ve only created a single food trend: pumpkin pie frosting made from pumpkin pie. I was the first person to ever make it and I’ve since seen it on countless blogs – so many that people no longer know to attribute it to me. When a trend becomes a trend, it can be hard to trace its origin.
One of my favorite trends right now is sour foods – sour beers, pickling things, and Korean fermented foods like kimchi. Americans have toyed with sour flavors – think ultra-sour kid’s candies, yogurt, some popular potato chip varieties, the occasional sour cream dollop, or sourdough bread – but as a whole, sour has been an under-explored flavor in the American palate until recently.
On my trip to Nashville, I became hooked on two of Olive and Sinclair‘s creations that use sour flavors to augment the sweetness of more traditional desserts. One was their sea salt and vinegar caramels (the inspiration for this post and a must-try treat) and the other was their buttermilk white chocolate bar (more on that soon). I wanted to share ways that you can hijack these ideas in your home kitchen outside of simply buying the candy (which you should totally do!).
I took the concept of the sea salt and vinegar caramels and turned it into a spectacular buttercream frosting that tastes like classic salted caramel but leaves your mouth with a surprisingly balanced sour note.
A few people to whom I mentioned this frosting concept seemed a bit grossed out by the sea salt and vinegar combination. I get it. I was turned off when I poured the vinegar into the caramel. The strong smell from the bottle got me more than a little scared. In the end, as you’ll see in my recipe footnote, I actually wish that I had added even more vinegar than I did. Once it mixes into the caramel, which then mixes into the buttercream frosting, the vinegar flavor ends up being very subtle – just a fun added complexity. You don’t even need to tell people it’s there unless they are the type of folks who love food trends; then, tell them all about it so your cool points can go up.
