1. Testing egg freshness. A fresh egg sinks in salted water, while an older egg will float.
2. Preventing sliced fruit from browning. Sliced fruit browning can be slowed down by adding lemon juice. Soaking the pre-cut fruit in salted water works likewise.
3. Oven spillages. Cover oven spillages with salt and continue cooking—this produces a crust around the spilled food that is easy to scrape off when the oven returns to room temperature.
4. Cleaning cast iron pans. Pour salt into cast-iron pans, make it into a paste by adding a bit of water, and scrub to clean. This paste can also remove rust, clean stained cups and plates, and even brighten copper pots. See more in the video below.
5. Pest Control. Keep bugs at bay by making a wall of salt at entry points which discourages insects like ants walking across it.
6. Removing red wine stains. Pouring salt over spilled wine can help remove red wine spillages by absorbing the wine out of the fabric.
7. Brine solution. Soak meat in a brine solution to make it more tender, like that thanksgiving turkey.
