This seasoning is very spicy and there’s no way to make it not spicy unless you change the recipe altogether.
You can use szechuan pepper instead of sansho, if preferred. The amount stays the same.
You can use dried orange peel or a mixture of dried citrus peel in place of the lemon. I like using the lemon because it’s a touch stronger, in my opinion.
For an easier way to get nori or seaweed flakes, you can crush half a sheet of dried seaweed to get the amount you need for this recipe. It tends to be the cheaper route as well, but you’ll have leftover seaweed sheets. They last a long time though!
You can do just white sesame seeds or just black sesame seeds. It doesn’t have to be both if you don’t have one or the other. Whatever you decide to do, it just needs to be a total of 4 teaspoons of sesame seeds.
