Do you mix the whey in before cooking the porridge or after? Wouldn't mind doing this.
After, as I use just microwave some oats, ~330g water -100g oats then add milk /whey after
could add water instead of milk, could also try it doing it on the hob with the whey in (done this, stuck to the pan and required more cleaning up), or in microwave (yet to try this, could asplode!?!?!?!
