Place in the oven at about 175–200 °F (80–100 °C), leave the oven door slightly open, and dry more than bake the doughnuts for 2½ to 3 hours.
Remove from oven and let cool.
Store in a dry place.

Add cold water to the gelatin, remove the excess water, and dissolve the gelatin in some of the strawberry purée, warmed.
