First things first, to make this delicious strawberry sauce, start by washing the strawberries to remove any dirt or debris. Then, trim off the stems and rinse them well under cold running water to ensure they are clean and ready to use.

Next, transfer the clean strawberries into a bowl, and add the sugar. Mix the sugar into the strawberries until evenly distributed.

Then, place the bowl onto the stove top, stirring constantly until the sugar melts, and the strawberries start to release their juices. This will take a few minutes, so be patient, and make sure to stir constantly to prevent burning.

As soon as the sugar has melted, the strawberries will start to release their juices, and you'll see the mixture start to become liquid-like. You need to continue to stir the mixture to prevent it from sticking and burning. As the sauce gets closer to a boiling stage, it will start to foam up.

Be careful during this stage and ensure that the pot is only half full because it can increase quickly and overflow.

Once the mixture has reached a boiling stage, reduce the heat to low and let the mixture simmer for five minutes. Do not overcook the sauce as this will cause it to lose its bright red color and become thick like jam.

After five minutes, remove the pot from the heat, and let it cool completely before proceeding to mash the strawberries.

When the sauce has cooled down completely, take a potato masher and mash the whole cooked strawberries gently. Don't overdo it; leave a few chunks of strawberry in the sauce. This gives the sauce a better texture.

Once the sauce is mashed, pour it into a glass jar and store it in the refrigerator for up to two weeks or freeze it for up to a year.
