My mom never craved crazy food, she craved SMELLS!!
When she was pregnant with me (and to an extent when I pregnant with my son, but it was much milder) she WANTED to smell anything related to candles, soaps, lotions, incense, air fresheners, you name it. She even wanted to smell bleach. Like if they went shopping, my father would make her sit in the car or stay at home because she would spend upwards of an hour in just the laundry or candle aisles.
There is a photo my dad took of my mom SITTING IN THE FLOOR OF THE STORE with a huge bottle of Raspberry Creme shampoo just sniffing it with her belly of me poking out. On the back he wrote "30 minutes of this! NO MORE KIDS!" (Needless to say my brother was born 2 years later XD) She also wanted raspberry anything. If it said Raspberry, she wanted it. I LOVE raspberries, my aunt has always teased me that my mom did that to me in the womb LOL
