Hahaha! When my dad’s dad’s mom passed, my grandma (her daughter-in-law) was given her recipe book & discovered that a small but key ingredient was missing/wrong quantity in every recipe her mother-in-law had ever given her, which is why things never came out quite the same for her. 🤡
Ha! I knew professional chefs who did this on the regular - not on their restaurant kitchens, but when contributing recipes to magazines and cookbooks.
