My vague recollection is that there are only four basic taste areas on your tongue (I remember salt and sour but can’t remember the other two). I also remember that holding ice in your mouth numbs some of the taste areas.
It could be that when you are eating cold food the “non-salt” areas are getting deadened slightly and the salt areas aren’t, which makes the food taste saltier. More specifically, all other tastes are lessened so the salt taste stands out more.
Since there are only four tastes, most of what we call “taste” is really smell. Cold food is probably giving off fewer vapors which means less smell. Again, the salt taste stands out more.
It’s been a long time since high school biology so this is a marginal WAG but I think I’m remembering correctly. Anyone with more recent knowledge feel free to correct me.
