One counterintuitive food storage tip is never put hot food directly in your fridge or freezer. Instead, leave it uncovered in your kitchen until it cools to room temp, then move it to your fridge.

The food will cool much faster in a well-ventilated room. A refrigerator is mostly an incubator and doesn't actually have much cooling capacity and is more designed to keep things cool, not make them cool. This will extend the shelf life of the food, prevent condensation, and also prevent other items in your fridge or freezer from warming up.
