In my experience, Brits can absolutely follow recipes from American cookbooks! There may be a few hiccups along the way, like translating measurements or finding ingredient substitutes, but it's definitely doable. The key is to understand the differences between American and British cooking terms and to find a reliable conversion tool for measurements. Overall, it's a fun and delicious way to explore another culture's cuisine. Just keep an open mind and a full spice rack, and you'll be good to go!
