The non-science thing I learned this year was espresso. This is now my favorite way to make coffee, but came with a huge learning curve. Latte art is difficult but makes me look forward to my latte. Espresso tonics with some citrus juice are also lovely.

I think because of science, I tend to enjoy hobbies that are very protocol-driven. I also really love espresso and espresso drinks. Here’s my first shaken espresso on my new setup - I find iced drinks more forgiving if I don’t have the grind quite right!
