I use four small teaspoons and it makes a very large loaf

That looks lovely the seeds would add variety. I have changed my recipe slightly and do not add the baking soda anymore just another teaspoon of yeast. Still add a bit of canderel as I feel it activates the yeast but now add inlulin to sweeten. My bread is now huge and can hardly fit in the bread slicer.

Yes it was perfect in the middle. My biggest problem with the bread machine was getting the loaf to rise but whatever I am doing its working for me.

I use 400g of water. I made another loaf today with same method. I look a photo before slicing.

I used 500g of flour. My problem was that the bread would not rise. I used inulin to try and get the yeast to react but it didn't work so tried canderel and it worked.

I made this recipe today with Fibreflour. I found it very hard to roll out and ended up patching it all together with my fingers in a cheesecake tin. I thought it was going to be a complete disaster but it turned out really good and only a small amout is very filling. I made a full quiche (x4) for all the family and they all loved the pastry.
