Crumble is the one recipe that worked in the microwave oven as good as in a gas oven. Sure the color resulted in pale yellow, not brown, but the color can be corrected if you have a culinary blow torch.
The crumble recipe is quite simple:
- baking flour 250 g
- butter 150g
When cooking in the microwave oven, do not cover the crumble. Your microwave oven should dehumidify so the crumble does not become soaked.
