Preheat the oven to 190°C (fan).
Line a large loaf tin (approx. 32 cm) with a single strip of baking paper so it covers the bottom and the two long sides. Leave the paper longer on both sides to act as handles for lifting the bread out after baking. Lightly oil the short ends of the tin.
In a bowl combine the gluten-free flour, teff flour, salt, sugar, yeast and psyllium husk. Stir well to mix the dry ingredients.
Add the warm water and oil.
Mix with an electric mixer using metal beaters for about 3 minutes until a thick dough forms.
The dough should be a very thick batter — thicker than cake batter but not kneadable like wheat dough.It should be soft enough to slowly drop from the beaters within 1–2 seconds when lifted.If the dough sticks firmly to the beaters and does not drop, add extra warm water 1 tablespoon at a time, mixing well between each addition, until the dough reaches this consistency.The dough should feel thick but spreadable and should not hold stiff peaks.The exact amount of water may vary depending on the flour blend used. Transfer the dough to the prepared loaf tin. Using a wet spatula, smooth the surface and shape the dough so it is slightly higher in the centre than at the edges. This gentle dome helps support the loaf as it bakes and can reduce a dip forming on top.
Cover the tin loosely with cling film and allow the dough to prove. In my kitchen this took about 18–20 minutes, but the time may vary depending on temperature. Watch the dough as it rises. The cling film helps trap warmth and moisture while still allowing you to see the height of the dough.If the dough starts to rise close to the cling film, remove the cling film before it touches the dough. After 20 minutes, check the height of the dough:If the dough is just below the rim of the tin, place it straight into the oven.If it is still clearly lower (about 1–2 cm below the rim), allow it to prove for another 5–10 minutes.Do not allow the dough to rise above the rim of the tin, as this can cause the loaf to collapse during baking. Bake for 45 minutes until the loaf is golden brown.
Remove the bread from the oven and lift it out of the tin immediately using the baking paper handles.
Carefully peel away and discard the baking paper, then place the loaf directly onto a wire rack.
Allow the bread to cool for at least 1 hour before slicing so the crumb can set properly.
