Don’t waste money on store-bought, pre-sliced apples. Those slices have been sprayed with a chemical solution, lessening the integrity of the apple (via Mashed). That perfect-looking fruit comes with a cost.
According to My Kitchen Escapades, water and salt help keep apple slices fresh for four to five days in the fridge. The site recommends dissolving half a teaspoon of salt in four cups of water. Then, add four to five cored, sliced apples to the water. Soak, drain, and pack the apples in an airtight container. My Kitchen Escapades claims that the taste of salt is undetectable in this fruit hack and Serious Eats adds that the browning risk is reduced, even after rinsing.
The outlet also says you can scale this recipe down if you don’t need that many apples. Instead of four apples, scale it back to one and reduce the amount of salt and water. Ensure you store the slices in an airtight container in the fridge, and mark it with the date. Labeling ensures you know how long the apples have been in the fridge and helps prevent foodborne illness (via Public Health MDC).
