You will need:
Yellow and orange things like half a banana, a little piece of pumpkin (precooked or canned version), 1 carrot, the juice of half an orange or a tangerin and so on.. I used all of those ingredients!
200g 0 flour
Step 1: Mix!
melt the yeast in orange/tangerine juice
add all to the flour, add sugar and work the dough for some time till you can do a thick ball
let it rest for 2 hours (sooner or later I will find the instant yeast)
