Minimising one's intake of carbohydrates tends to deprive one of some rather lovely culinary items such as pasta and bread, because grains contain a lot of carbohydrates thanks to the high amount of starch in them. Typical substitutes are non-grain flours such as almond flour or coconut flour, but those come with their own problems - a distinctive taste (especially for coconut), a crumbly texture and they're around 20 times as expensive.
Since I can happily eat gluten and gluten is not just apparently the key to the typical texture of wheat-based dough products but also a protein with rather low carb content, I decided to try and make a flour substitute mix that I can use more or less like wheat flour with the help of vital gluten. However, I am unsure about just using pure gluten as a flour substitute - partially because there's a lot of claims about its inflammatory properties even for non-coeliac/intolerant people and partially because I sort of just assume there's a reason nobody seems to be doing it.
Because of that I wanted to ask whether there was an easily available, halfway affordable and low-carb (let's say under 8%) edible substance that I can use as a bulk base for my flour substitute which doesn't have weird reactions when used in baking or noodle making and isn't too far off in terms of taste (as a scale: I can tolerate almond flour, but coconut flour is too much for me outside of cake). I'm considering adding some psyllium husk to jack up the fibre content, but I don't think it's suited for this purpose. Advice as to the ratio for mixing is also appreciated.
