NO evaporated milk wont make it taste sweet (at least you use a sweet one they might sell that side) but here evaporated milk tastes like milk but thiker, is something in between cream and milk.
I talked to a Peruvian person I know and she told me papas a la Huancaina can only be made with yellow peruvian chilli (aji), cause thats kinda the most important ingredient that will give the dish that special taste. Here in my country of course we can get such ingredient due to we are pretty close lol... but still is such a great dish you would die!!!! lol this guys they really know how to cook im tellin ya (I´m gonna tell you about some other great peruvian recipies later, specially if you like fish) ok I can go on and on cause we are kinda the continent of potato! lol hey have you thought about moving here??? hee hee
Love you dear! have a great weekend.
