Can i use muscovado sugar for kimchi instead of caster sugar?

Yes, you can use muscovado sugar in kimchi instead of caster sugar. Muscovado sugar has a richer flavor due to its molasses content, which can add depth to the taste of the kimchi. However, keep in mind that it may alter the final flavor profile slightly. Adjust the quantity to taste, as muscovado sugar is generally less sweet than caster sugar.
