In a bowl, mix almond and flax seed flour, konjac flour and salt. Add cream cheese and cold butter, cut into cubes and mix (either by hand or in a blender) until butter is the size of a pea and the mixture slightly crumbles. Add scrambled egg and vinegar and stir to combine everything.
Transfer to a floured surface and knead lightly until a compact lump is formed. Wrap in cling film and refrigerate for 1 hour.
After one hour, take it out of the fridge and preheat the oven to 200°C.
Place the dough between two baking papers and roll out to a diameter of about 25 cm. Carefully remove the dough from the paper and transfer it to a round pie pan. Carefully shape the edges and bake for 10 minutes.
Then let it cool, lower the oven temperature to 170°C and start preparing the cream.
