Skimping on the moisture component is a major sandwich-building no-no. No one likes biting into a dry sando. However, that moisture component means (shocker) wetness - and when water molecules get trapped with no place to go, it can lead to soggy bread. For this reason, ditch the plastic sandwich bags for wrapping and storing your sammies. Whether packing a lunch or storing sandwiches for later enjoyment, plastic sandwich bags and plastic clingfilm both trap moisture inside and cause the bread to become soggy.
"The biggest culprit in the kitchen is moisture, and it can sneak in faster than you think," Smith says. "Never measure spices directly over a steaming pot or pan. Steam will enter the container, create condensation, and cause clumping, mold risk, or flavor loss. Instead, spoon the amount you need onto a plate or into your hand, then add it to your dish. Also, make sure your measuring spoons are completely dry before dipping into any jar."
