If it’s any use to you, I have found that a mix of lemongrass and Thai basil is a very reliable substitute for coriander in most contexts. I love coriander personally, but my sister can’t stand it

Supposedly Vietnamese coriander (Persicaria odorata) tastes very similar too while not actually being in the same family of plants as coriander, so it might be worth a shot. I’ve never tried it myself though
