I am a die-hard fans for preserved fruits. If having a craving for preserved fruits indicates that you are pregnant, then I must be pregnant since Kindergarten.
Well, the story is, I spent a good part of my childhood living with my Grandma, and thus I pick up my love for many traditional food found in chinese families like sour plums, and mee hoon guai.. etc
Anyway, 100g of 乌梅, a kind of sour plum is around 219kcal. The calories of other plums that taste saltier or less sweet should be around there. (Think + - 50kcal)
