A turkey sandwich with mayonnaise should be eaten within three hours if not kept cool. Mayonnaise has a tendency to spoil rather quickly at room temperature.
When using mayonnaise as a sandwich spread, it's important to keep it refrigerated to prevent bacterial growth, especially if the sandwich will be stored for a while. Additionally, use clean utensils to avoid cross-contamination and ensure the mayonnaise is fresh, as spoiled mayo can lead to foodborne illness. Lastly, consider the temperature of the sandwich; if it's left out for too long, it should be discarded to ensure safety.
You can, but it would probably taste bad. (Hot mayo?)As long as it's mayonnaise out of a jar, not home-made, you can put a sandwich with mayonnaise in it on a sandwich grill, or in a frying pan, and it's great.Using a microwave, mayonnaise should be mixed, because otherwise its high fat content will cause it to heat before the other ingredients.
