Seniors Brendan Huang and Carolyn Hong, who both have received the COVID-19 vaccine and are in the same social bubble, met in an organic chemistry lab as sophomores, became fast friends and wound up baking sourdough bread together. It’s an adventure that Hong calls “our sourdough journey.” (Photo by Talia Patt)

Friends Carolyn Hong and Brendan Huang had a delicious...
