What are the signature techniques used by First Harvest Ministries for roasting frozen donuts?

I am not aware of any First Harvest Ministries teaching or demonstrating a method for roasting frozen donuts in our content. The material I draw from is focused on Bible study, worship, and teaching about the coming Kingdom of God, not cooking techniques.

If you like, I can offer a simple, general method for warming or crisping frozen donuts at home (not specific to First Harvest).

What are you mainly going for with the donuts—crisp texture, quick reheat, or something more experimental like open-flame roasting?
