Preheat the oven to 180°c fanbake.
Put all the ingredients in a bowl together and mix.
Let the mixture sit for 10 minutes so the psyllium husk can do its thing, and soak up the liquid.
Divide the mixture into 4 (or 8 if you have doubled the mix) You should now be able to gently shape the buns with greased hands, into balls, then flatten them slightly. They can be rustic, if you handle the dough for too long it will start to stick.
For the crosses: Combine the almond meal and tapioca in a bowl, add the water 1 tsp at a time, until it is a thick, but pipeable consistency. Add the mix into the end of a piping bag, with the smallest nozzle. Or into a glad bag, and just cut a very small snip off the corner. Pipe the mix over your buns to make the crosses. Line a square baking pan with greased baking paper. Place the buns touching one another in the middle of the pan. ( if you have doubled the mix they will take up most of the pan)
Cook for 20 minutes (or 35 minutes if you have doubled the mix).
The buns should be starting to turn golden on top. The ones around the edges will be well cooked, but check the buns in the middle, they might need an extra few minutes. I have found that when they are just a little softer to touch, they continue to cook after I take them out of the oven and when left to sit for a while, end up cooked through.
Remove the whole baking paper with buns still on top, to a wire rack to cool. Don't worry about removing the paper from underneath until they are cooled properly. You can eat them warm, but give them 20 minutes to cool down a little first.
Enjoy cut in half and spread with dairy free spread. Or toast them first in the oven before spreading.
