Making your own fruit sauce is a perfect way to use up excess fruit from the garden. Fruit sauces can be poured over desserts, such as cakes or ice cream; thickened up to make jam; or drizzled over meat dishes. For example, pour pineapple fruit sauce over baked ham or pork. Add cornstarch to fruit sauces that need thickening. Always mix cornstarch with a cool liquid before adding to ensure that it doesn't clump up in the boiling fruit mixture.
Clean berries and de-stem them, if necessary.
Add the berries, fruit juice, the juice of 1/2 of a lemon and sugar to a saucepan. If you are using strawberries, cut the berries into smaller pieces.
Boil the fruit mixture until it has reduced significantly, stirring frequently. As the mixture reduces and the liquid evaporates, the fruit will start to thicken.
Mix 4 tsp. of cornstarch with one to 2 tsp. of water to make a thick paste. Mix the paste into the fruit mixture.
Continue to boil the fruit mixture until it has reached your desired consistency.
