Preheat your oven to 170C
Using your TM (turbo 3-4 times) or hand held mixer/food processor, mix well khorasan flour, bicarb soda, baking powder and sea salt - Leave aside
Whizz in your TM bowl (speed 4, 1 min) or use a hand held mixer, food processor until well mixed - bananas, eggs and butter.
Add cultured cream (or sour cream, kefir cream, buttermilk, or kefir milk)
Add all of the flour mixture above
Mix well but do not overmix or your bread will be tough, for TM use speed 4-5, 20-30sec only.
Optional, add pecans and/or couverture choc chips (Callebaut, Valrhona...)
Mix well by hand is my preference but you can use your TM on reverse 10 sec speed 6
Put in your buttered and lined loaf tin, I use my medium size tin, measuring (25x12cm and 10cm high).
Bake for 1-1hr 15 minutes until brown and a skewer inserted in the middle of your cake comes out clean.
