When I make potato salad, macaroni salad, tuna salad, and sometimes ham salad, it seems like there's always a puddle of excess liquid at the bottom of the storage container the next day.
Does anyone know what is causing this or how to prevent it from happening?
I always cook the pasta in water with oil to limit absorption, and I always try to drain it thoroughly. I also always use regular mayonnaise or salad dressing instead of the light ones which have more water in them. A day later, I am always draining off the excess liquid and remixing with mayonnaise all over again.
The supermarket salads never seem to have this problem: what are they doing differently? Can anyone help???
