Ingredients for Raspberry Sauce

This versatile sauce only calls for seven ingredients, and you don’t even need fresh raspberries to make it! Our recipe only requires a little bit of sugar, which means the natural sweetness of the berries really shine. 

Here are the ingredients you will need to make this sweet and tart raspberry sauce:

  • Frozen raspberries. This means raspberry sauce can be enjoyed year-round (not just during raspberry season!). See notes if you prefer to use fresh raspberries. 
  • Water. This thins the sauce and helps the berries break down as they cook. You will also need a little bit to make the cornstarch slurry.  
  • Lemon juice. A little bit of lemon juice will add a bright, acidity that’s very subtle when it comes to the flavor of the sauce.
  • Granulated sugar. To enhance the sweet flavor of the raspberries. 
  • Cornstarch. This ingredient helps thicken the sauce so it turns into a spreadable, smooth sauce. 
  • Vanilla extract. A splash of vanilla adds the most subtle vanilla flavor that takes this sauce to the next level!

Pouring water over into the saucepan.

In a medium saucepan over medium heat, combine the frozen raspberries, water, lemon juice, and sugar. Bring to a low boil and cook, mashing the berries with a rubber spatula or spoon.

Make a slurry in a small dish by mixing the cornstarch and cold water. Temper the slurry with 2-3 tablespoons of the raspberry mixture, then slowly stir it into the saucepan. Cook for 3 more minutes until the sauce thickens. 

Transfer the sauce out of the small saucepan into a dish or pitcher. Serve the sauce, either warm or cold. It will thicken as it cools.

Tips for Success

  • Using fresh raspberries: To make a fresh raspberry sauce, substitute the frozen raspberries with 5 cups of fresh berries.
  • Removing seeds from the sauce: For a smooth, seedless sauce, transfer the sauce into a fine mesh sieve set over a bowl and use the back of a spoon or a silicone spatula to force the berries through the strainer to remove the raspberry seeds.  Discard the seeds.

  Storage and Reheating

Store leftover raspberry sauce in an airtight container or small jar for up to one week.

Reheating raspberry sauce: To reheat, warm the sauce in a small saucepan over medium heat, stirring often. You can also microwave the sauce in 15-second bursts until warm. 

You can also freeze this sauce. Place it in freezer proof containers and freeze it for up to six months. Thaw it overnight in the fridge. When the sauce thaws, it will be a bit thinner because cornstarch loses its thickening power after it gets frozen.

How to Use Raspberry Sauce

​A favorite way to use this sauce is as a sweet and fruity cake filling! All you need to do is to pipe a dam around the perimeter of the cake, then fill it with the sauce.

However, this sauce has so many uses- from special occasion desserts to the everyday recipes we make on a regular basis.
