One of the favorite winter delicacies in Japan is “shirako”, cod fish sperm sacs. Shirako looks a lot like a piece of human brain, white soft, squishy and very slippery. Most Japanese appreciate its light, delicate taste, with enough fishiness to remind you that it’s not a dairy product.
The sperm sacks may melt in your mouth like soft butter, but it is said they have just the opposite effect on men who want to perform better in the bedroom. Despite this, very few western men rarely try this Japanese delicacy.
