The problem was when we lost our smell, coffee tasted worse (basically only the bitterness stayed, no aroma).

The same was true for sweet and salty foods. The salty taste still comes through, but no smell. So junk food was the only thing with any taste (since it mostly tastes like salt and sugar anyway).

TLDR: Acid, salt and sugar still came through, but umami, fruit and tasty veggie smells were all gone for our family.
