Having discovered these Japanese octopus balls in a British fast-food chain, I decided to have a go at making them myself at home. It was surprisingly easy. However, I didn't happen to have an octopus in the fridge or freezer. TBH, it was the balls I particularly liked rather than the octopus anyway. So, what else could I use as a filling? I searched the internet and found various suggestions - sweet and savoury - but the one I liked best was kimchi, so that's what I used instead of octopus. Have you had a go at making takoyaki and if so what fillings have you tried? PS: I realise that 'tako' is Japanese for 'octopus' so if you're not using octopus then they're not really takoyaki but what the heck.
