Gluten flour
Does anyone know if there's any way to substitute gluten flour with something else (like you can add something to AP flour and get cake flour)? I need wheat gluten flour with at least 70% protein, but everywhere I checked, there is no gluten flour. I need it to make gluten balls (麵筋). In Chinese market, they have 高筋, 中筋, 低筋, but I have no clue which one to get and I don't even know if the English translation is accurate or not.
