Step 1Move the oven rack to the centre position of the oven, and preheat to 190 °C/ 375 °F (conventional), or 170 °C/ 340 °F (fan assisted). Add the dry ingredients to a large bowl and thoroughly whisk to combine (ground flaxseed, coconut flour, caraway, baking soda, Erythritol, salt and xanthan gum or ground chia seeds). It is especially important to evenly distribute the xanthan gum (or ground chia seeds).
