For the best part of the last five years I have lived in Thailand. In Thailand, gluten free rice-based dishes are commonplace and ingredients are mostly purchased fresh everyday at ‘wet markets’.
Outside of big cities, western dishes are not so popular, and equally-so gluten-free alternatives simply don’t exist.
Whilst living in Thailand, I would rarely eat any gluten free breads or biscuits because my local supermarket didn’t stock them. I made do without.
