How to Thicken a Fruit Sauce

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.

Step 2

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.


Step 3

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.

Step 4

Mix 4 tsp. of cornstarch with one to 2 tsp. of water to make a thick paste. Mix the paste into the fruit mixture.

Step 5

Continue to boil the fruit mixture until it has reached your desired consistency.
