Do not roast it.
Do not overheat it
Do not make it too thick as the heat can not penetrate to the core of a large chunk. maximum 2 or 3 centimeter thick. If you make it large chunks, then after 30 minutes in the oven remove it and slice it to make the heat reach the core and return it back to the oven another 30 minutes.
by roasting I mean do not make the flaxseed exposed direct to the heat source. If you do , it will smell like fish and turn to bitter taste. maybe because of the high omega 3 contents.
keep the oven at 220 degrees Celsius. I am not sure about the 220 but this is what I set the oven at in my electrical oven. The bottom line is as low heat as practical.
if you get a bitter taste or any fish like smell, then you either have over heated or roasted the flaxseed.
you will find so many recipes in the net. all not required.
Only flaxseed and water.
you can add coconut oil or olives oil and eggs. but you will get a good bread with flaxseed and water only.
for each cup I add half spoon of cinnamon and half spoon of ginger and half spoon of garlic mixed together to hide the remaining bitter taste of the omega 3.
I do not recommend using Stevia but it help hide the bitter taste as well.
