Sour Dough, mixed in TMX, baked in Bread Machine, NO ADDED YEAST

The Good Loaf,  sliced.

FAILED                 

                                                                                        SUCCESS

I set my self this challenge.  To make a Sour Dough loaf,  mixed in TMX and Baked in the Bread Maker.   99% of recipes for making Sour Dough in the bread Maker have added dry yeast.  The one article that didn't ,went into a complicated method of mixing the dough, switching off the bread maker,  and then resetting it to bake,  for the next day.
As you will see from the 2 photos attached,  the first attempt was not a success.  The second loaf,  although not cut , at this moment, was a success.  The good loaf was made in the one day,  and had only one rise.  This will be very handy in Summer when I don't want to heat the kitchen with the oven.  It will also save electricity. This recipe was developed for forum thermomix members. who have Bread machines.

375g bakers flour, (I use Laucke , Crusty White Bread Mix,  this has the sugar and salt added )
! teaspoon of each salt and sugar if NOT using a mix.
300g of active Sour Dough starter.
100/150 g.  warm water.  This will depend on how wet your starter is.

Do
Place all above in TMX bowl and knead for4 mins.
Tip on to Silmat that has been lightly floured,  and fold on itself several times.  It should be a soft dough,  but easily handled.
Place in Bread Machine bucket which has the paddle removed,  and is lined.
Spray with water and sprinkle with sesame seeds.  (the seeds will prevent the loaf from sticking to the sides of the bucket as it bakes.)
Cover with plastic.  I use a shower cap.
Leave in a warm place. ( between 20/25 o) to rise.  Mine took 5 hours,  could take up to 6.
Warm the inside of the Bread Machine 10 mins before you are ready to bake.  ( I heat a wheat bag in the microwave for 5 mins , and place this in the machine.)
Spray loaf with more water , and gently place in machine.
Bake for 1 hour and 10 mins.  ( this will vary depending on machine.)
Cool on rack.

I have just cut this loaf and it is perfect.
