How do you fix bland potato soup?

The only thing that will make any steak "absolutely tasteless and chewy" is overcooking it. At a certain temperature, the muscle cells contract and squeeze out the juices. It's simple physics. Don't fight Mother Nature.

I would recommend coating your cooked jerky lightly with olive oil and then sprinkling with dry rub or seasoning of your choice. The oil will help the rub stick and will still keep your jerky from going bad. Continue to store jerky in an airtight container or zip lock bag..

Lumpy mashed potatoes generally indicate undercooked potatoes. If you get to this point and realize you've undercooked your potatoes, just add a little bit of milk or cream, then cook the potatoes over low heat until the lumps begin to soften..

Salt the water generously. If you don't add enough salt, the potatoes will be bland. It's surprising that such a simple ingredient would make a big difference, but it will. Adding salt to the cooking water also helps the potatoes could faster and break apart better, resulting in fluffier and creamier mashed potatoes.

If a soup is tasting bland in the bowl, consider adding acid rather than salt. A squeeze of lemon or lime, or a dash of yogurt or sour cream can add brightness to the bowl.

When a dough formula is lacking in salt, the flavor of the finished crust will be bland, and it might even take on something of a starchy taste. You might be really surprised to see how much a simple adjustment in the salt level can improve the crust flavor when the amount was originally too low.
