I have a really hard time telling when milk has gone bad.
It ALWAYS smells sour to me, no matter when I smell it, so that’s no good.
I have OCD and anxiety, so unless the milk is hella sour, I can’t quite tell if the milk tastes funny because it’s off or if it tastes funny because I’m freaking…
I had this same problem till my mother showed me this trick. All you need is to take the smalest pot you have, pour into little of water(you don’t have to but it do good for your pot) and then some milk. Next warm it up and if nothing happens - that means your milk is still good. If not it will alike water and milk have a fight and try to seperate themself(at lest that is have it’s looks for me). Also your milk can smell funny becouse of what the cow(s) have to eat(too much grass or too much hemicals&medicins, first is safethe second will cost you a little).
And most of humans beings have in some level of intolerance of the milk orther tham human one. The best is to not eat milk powered and product made of it. When in the glass of milk you have there mostly water and very little of lactoz, in the powered it’s almost all lactoz(it’s what makes milk withe by the way) and little of minerals&viatmins that haven’t been lost in the proces of production. Most of cheap chocolad product have it and some of instant meals(cheap ice-cream don’t have ever milk in them :< it’s coco butter) and ever sometimes bakery products have them(for what they needed milk in weath bread I’ll never know).
