This is a very nice example of open source - the sharing and local adaptation of recipes is what makes culinary culture so interesting.
However, so far there is not much in this challenge (yet) from a circular economy perspective.
Let’s try to work out how to add that element in, so that it fits within the framework and goals of the OSCEdays.
For example, you could try to find recipes and processes which use ingredients that are commonly wasted or overlooked.
Or you could try to ‘align’ different cooking processes in the way in which we want to align industrial and other production processes. So, for example, a roast chicken recipe might be linked to a soup recipe, where the leftover bones from the chicken are used to make the stock for the soup. See for example @Denis’ challenge from Berlin, showing the resource relationship between beer and bread:
It would be great to have a recipe book which is not only about the cooking, but also helps the reader think about the whole food system. You can show how people can start to build mini-circular-economies within their own kitchens, gardens or window sills. You could show how to effectively compost food scraps, or farm worms and [insects][1] fed with kitchen waste.
Through recipes and tutorials, you could highlight particular local ingredients, herbs etc which are well-suited to growing at home.
Does anybody else have suggestions for how to add a circular flavour to this challenge?
