Hi actually im making hot cheese sauce but i think it is not suitable because i tried to lower the pH untill 4.0 by adding citric acid unfortunately taste of creamy cheese is kinda gone..before this im using vinegar because it was really sour then i tried change to citric acid cause i read it doesnt change the flavour but its still change the flavour..is there any way to make my hot cheese sauce pH lower than 4.0 but not changing the taste and flavour?
