I have 4 potatoes with skin that have been washed and poked. I would like to know how can I safely keep them until tomorrow? 

To safely store your prepared potatoes until tomorrow, follow these steps:

1. Wrap Each Potato: Individually wrap each potato in aluminum foil or plastic wrap. This helps retain moisture and prevent them from drying out.
2. Refrigerate: Place the wrapped potatoes in the refrigerator. Keeping them in the fridge slows down the growth of any bacteria and helps maintain their freshness.
3. Container Option: If you prefer, you can place the wrapped potatoes in an airtight container or a resealable plastic bag before refrigerating them. This adds an extra layer of protection against odors and contamination.
4. Label (Optional): Label the container or bag with the date to ensure you remember when you prepared them.

These steps will keep your potatoes fresh and safe to use for up to 24 hours. When you're ready to cook them, you can proceed with your preferred cooking method.
