Korokke, or Croquette as we know them, are delicious squishy bundles of meat or veggies, enrobed in crispy panko breadcrumbs and cooked until golden in oil. They're mouthwatering-ly wonderful, and a firm favourite in Japanese households. Traditional korokke often use a meat mix for their filling, but pumpkin is also a popular choice - or more often Kobocha Squash, which is very similar to pumpkin, but much harder to get hold of in the UK.
Right now you might struggle to find any pumpkins on the shelves, but a nice summer squash is a great substitute. Korokke also keep well, so if you cook some in the evening they'll still be delicious when served at room temperature in a bento box the next day - even better when dipped in spicy mayo!
