If making this ahead of time, I recommend cooling to room temperature, then freezing and reheating before serving. These naans are best served immediately but are great when reheated.
Store in an airtight container or Ziploc freezer bag and freeze leftovers.
I recommend using gluten-free bread flour made from gluten-free wheat starch. Other gluten-free blends will most likely give different results and may not turn out.
