I couldn't find แป้งท้าวยายม่อม from the Vietnamese market in this area in CA, can I use some other flour instead? They have rice flour mix with corn flour and rice flour mix with tapioca flour, etc. What is the replacement of แป้งท้าวยายม่อม if I can't find แป้งท้าวยายม่อม? Thank you for the video, I have been looking for this dish for a long time.
