Cucumbers. Especially delicious on a bagel with cream cheese.
When I was younger I used to salt and eat apples and tomatoes whole.
Salt is used as a universal flavour improver because at low concentrations it will reduce bitterness, but increase sweet, sour and umami, which is desirable for sweet recipes. But at higher concentrations it suppresses sweetness and enhances umami, which is good for savoury things.
Oatmeal. Add fresh or dried fruit, ginger, nutmeg, cinnamon, allspice, peanut butter, and salt while cooking. Sometimes a dash of brown sugar if low on fruit or the fruit I have isn’t very sweet.
Apples
Always get hate for it, but it tastes good
