What precaution must you take when using mayonnaise as a sandwich spread?

Here are some precautions to take when using mayonnaise as a sandwich spread:

* Food Safety:

* Refrigerate properly: Mayonnaise is a perishable food and needs to be kept refrigerated. Do not leave it out at room temperature for extended periods.

* Use fresh ingredients: If you're making your own mayo, use fresh, high-quality ingredients.

* Avoid cross-contamination: Wash your hands thoroughly before handling mayonnaise and keep utensils clean.

* Don't reuse an opened jar: Once opened, mayo should be used within a few weeks (check the label for specific recommendations).

* Don't use if it smells or looks off: Mayonnaise can go bad, even in the refrigerator. If it has a strange smell or looks discolored, discard it.

* Allergy Considerations:

* Egg allergy: Mayonnaise is made with eggs, so it's not suitable for people with egg allergies.

* Other allergies: Some mayonnaise may contain other allergens like nuts or soy. Always check the label carefully.

* Storage and Handling:

* Store in the refrigerator: Always store mayonnaise in the refrigerator after opening.

* Use a clean utensil: Use a clean spoon or knife to scoop out mayonnaise. Don't use the same utensil to put mayo back in the jar after it's been used.

* Don't expose to heat: Mayonnaise can separate or become runny if exposed to high temperatures.

* Taste and Texture:

* Avoid overusing it: Mayonnaise can be overpowering if used in large amounts. A little goes a long way.

* Consider your sandwich: Mayonnaise is best for sandwiches with fillings that don't already have a lot of moisture.

By following these precautions, you can enjoy mayonnaise safely and delicious in your sandwiches.
