If you can’t find toasted nori strips, fold the nori sheets a few times then cut them into thin strips 1cm in length or break them up into small pieces in a mortar and pestle, then pop them into a bowl.
Lightly pound the sesame seeds just a couple of times in the mortar, just enough to release the flavour, then add them to the bowl.
Add all the remaining ingredients to the bowl, except the chilli flakes and salt.
Add half of the recommended amount of chilli flakes and salt, taste, and then if you wish add the rest. You can always add more – or you can skip the chilli if you’re not a fan.
Combine well and store in a glass jar or air-tight container for 3-6 months.
If your furikake tastes stale during that time, spread it out onto a pan and pop it into the oven for a minute to wake up the flavours.
