Place the almond milk in a large bowl along with the all purpose seasoning, black pepper and pink salt.
Carefully lower the chicken into the milk.
Wrap the bowl with saran wrap/cling film and refrigerate for several hours or overnight.
In another separate bowl, add the sorghum flour, millet flour, tapioca starch, baking powder, all purpose seasoning, paprika, onion, garlic granules, chilli powder, parsley and pink salt.
Mix the flour(s) together so all of the ingredients are evenly combined.
Do a quick taste test to determine if you need to adjust for more seasoning.
Carefully remove the chicken from the milk (do this one at a time) allow them to drain in a separate bowl or plate.
Dredge the chicken in the flour mixture (shaking off any excess).
Dip the chicken in the milk (allow to drain over the bowl) and then dip it one more time into the flour blend.
Repeat the above steps with the remaining chicken.
Once all of the chicken thighs have been coated, allow to rest on a plate for 10-15 minutes.
Transfer them to the air fryer basket (you may need to do this in batches).
Air fry 200C/400F for 20-25 minutes turning over half way through.
Check the chicken about 5-8 minutes before it has finished air frying and spritz any dry spots with oil.
Once cooked transfer on a plate with baking paper (leave for about a minute) before transferring to a cooling rack.
