Cakeability for lightening nut-flour baking

There used to be a product Cakeability Expert Foods: Wise Choice Cake-ability Baking Aid which was prohibitively expensive but used to lighten up nut flours in baking.

I found a home version of it here Cakeability? = Add in for cooking with nut flour - Low Carb Friends and founds some reports it works well. Could be interesting to try adding in with our baked goods.

1/4 cup egg white powder (like JustWhites)
1 tsp xanathan gum
1 tablespoon baking soda
1 Vitamin C tablet - crushed. Or 1 tsp powder

I crushed the vitamin C in a coffee grinder.

Someone on this board posted it and it works beautifully.
1/4 cup per 1 cup ground nuts.
