Explanation
Is there a variation between store-bought and handmade potato salad in storage time?
It is debatable. Salads from the store frequently keep their texture for a long time.
In that aspect, homemade dishes aren’t necessarily the best. But it is all up to when the dressing separates.
Many websites discuss the distinctions between commercial mayonnaise/store-bought mayonnaise and homemade mayonnaise and oil or mayo-based dressings, although, in some situations, the changes are minor.
What is important here is whether the dressing’s texture is being kept or not.
So, there is a tip: To avoid dressing being broken down/separated after 2 days in proper storage, you can try to make the dish without dressing.
Adding it later before serving will eliminate the separating situations that can likely ruin your delicious food!
The tip is the solution for the query: can you make potato salad the day before? Because it is a yes, as long as you keep the dressing out until the enjoy time comes!
