It's delicious, but it goes off quickly. I only like mayonnaise if it's cold. The mayonnaise that's on most things now isn't really mayonnaise, it's some chemically concocted thing that tastes like mayonnaise. I used to work at a sandwich shop so i know. Real mayonnaise cannot be left at room temperature, it goes off so quickly, but there is a synthetic mayonnaise, called "miracle whip" here in the US, i'm sure it has different names in other countries used by most shops that you can leave out at room temperature, and won't risk food poisoning.

It's not as good as real mayonnaise though.

My favorite sandwich is turkey and swiss on rye, and i can't eat it without real mayonnaise.
