Ok my loves. I am leaving the details out as you need to experiment to get this right for you.
3 bananas frozen and then defrosted.
10 grams live yeast ( 5 grams dried)
10 grams salt
325.ml warm water
400 grams light malted flour
Dark swiss flours add to as needed ( maybe 200 grams
Freeze old brown bananas
When you want to make the bread defrost bananas
And mix with the yeast, water and light melted flour.
Leave for 10 mins
Add the salt and start adding dark swiss until you get a good dough mix. Like me you have made enough bread to knoow when ypu have added enough flour you dont need need to tell you
