Do you mean dried coriander Corinne? Because coriander and cilantro are the same plant. I’d just leave out the dried coriander if that’s your plan and replace it with some fresh parsley or nothing at all. –Rachel

If I sub coriander for cilantro, how much should I use?

You’re welcome Corinne–and if you are referring to dried over fresh spices and herbs, always use half as much of a dried item than the fresh calls for. I’ll make a note to add the equivalencies moving forward. –Rachel
