For preparing various dishes, only a few tablespoons of tomato paste are often required.
After using it, the question arises: what to do with the leftover jar of sauce?
An effective way to keep the product fresh for a long time is freezing.
However, for various reasons, this method may be inconvenient.
Therefore, experienced cooks have found simpler, yet equally effective methods.
Mustard
To use mustard as a preservative, you need to coat the neck of the opened jar of tomato paste with it.
You should also cover the inner surface of the lid with a thin layer of mustard.
Vegetable Oil
To prevent the sauce from coming into contact with air, which leads to spoilage, you can use vegetable oil.
Add a little oil to the jar of tomato paste so that it completely covers the top layer of the sauce.
Thanks to these methods, the quality and taste of the product will be preserved for a long time.
