Like most of the internet, I’ve gotten a real kick out of the Tik Tok videos of Dylan Hollis. The vintage style aficionado and self-described amateur food historian has carved a space for himself on the internet with his bombastic personality and humor while testing out recipes spanning the 1800s to early 2000s.
The recipes he tries vary wildly in quality, and the recurrence of typically timely ingredients (especially lard and gelatin) regularly turn into comedic gold. More than once, Dylan strikes oil in his search for tasty recipes (“magic” peanut butter cookies and an eggnog recipe from the 1800s spring quickly to mind) and I sometimes use his videos as inspiration for things I can make at the pie shop.
Most often, I find myself intrigued by the recipes he picks and the trends they exhibit. WHY so much lard in everything made before the 60s? Why so much gelatin in mid-century America? Just HOW freaking high, lonely, horny, or all three must someone have been to create the “Candlelight Salad?”
The answer is, simply, that these recipes- like the books, movies, and music that were enjoyed then- are products of their time. Foodways are a part of culture and one can track the history and trends of a period of time as easily in a cookbook as you could a textbook.
