Usually found in little sachets within packages of kabayaki eel, served sprinkled on top of yakitori for an extra kick or as a seasoning for sushi, sanshō is Japan’s answer to the now world-famous Szechuan peppercorn from south western China. Whilst not related to peppercorns in any way, they’re both berries from prickly ash trees and share the pepper monicker due to the spicy, fiery slow-building heat that they impart to food. The flavour of sanshō starts with a peppery grapefruit scented awakening of the saliva glands and passes through fizzy, cooling, electric sensations before calming into an almost anaesthetic numbness, a long lasting souvenir of the food you’ve eaten. Not an immediate heat like you would get from a chilli pepper, but a more subtle experience, delivering its nuanced qualities in waves.
This complex spice doesn’t often get to make an appearance in sweet dishes, being mostly recognised as a savoury flavour, but while experimenting with making some gingersnap cookies we stumbled across sanshō’s affinity for buttery, crisp biscuits, and haven’t been able to stop making them since. Imagine German pfeffernüsse, kruidnoten of the Netherlands, or the gingerbread men from England, but with a zesty lemony aroma and a bit more punch and you’re getting close to these spicy little treats. They have a firm, crisp snap, and a wonderfully crackled surface, perfect for wrapping up as a homemade gift for loved ones or for serving with a cup of tea.
