oven type would be nice

[DO1JLR]

Hello

Thanks for the Open Recipe format, it looks pretty cool and I'll try to use it for my collection of waffle recipes soon.

I would have a small feature request. It would be very cool to specify the "oven type". I imagine here a string or possibly even an array of different options.

# Example Values
oven_type:
  - "any".
  - "conventional oven
  - "microwave"
  - "wood stove"
  - "waffle iron"
  - "stone oven"
  - "grill"
  - ...

currently in my draft, I solved this by setting 'X-oven_type: "waffle iron"', but of course I hope for a official solution. :wink:
