What You Need

You can find the full printable recipe, including ingredient quantities, below. But first, here are some explanations of ingredients and steps to help you make this recipe perfect every time.

Here are the ingredients you’ll need for this recipe:

  • Cornstarch — This my thickener of choice. Substitute arrowroot powder or tapioca starch.
  • Granulated sugar — for a healthy blueberry sauce, use either a zero-calorie sweetener (such as monkfruit) or use coconut sugar.
  • Water — adding just a bit of water creates a nice consistency.
  • Blueberries — Fresh or frozen blueberries work great.
  • Lemon juice — lemon and blueberries are a nice flavor combination and we’re adding just a bit of lemon juice (fresh or bottled) to enhance the sauce’s flavor.

What Blueberries are Best for Blueberry Sauce?

When buying fresh blueberries, choose berries that are plump and smooth-skinned. The color of the berries is an indicator of ripeness (not the size of the berries), so choose berries that are deep purple-blue. You can use fresh or frozen blueberries with this recipe. Frozen blueberries are great because they’re frozen at the peak of ripeness and they hold their shape better while cooking.

Frequently-Asked Questions

How do you thicken a berry sauce?

Cornstarch is a great thickener for a berry sauce because it creates a perfect consistency. If your sauce is too thick, add a little more water or if it’s too thin, you can add cornstarch combined with water and bring the sauce to a boil.

How can I thicken sauce without cornstarch?

Cornstarch is a favorite thickener, but there are options you can use besides cornstarch. For example, agar agar flakes make a great zero carb thickener. You can also use arrowroot powder and even tapioca starch as a thickener.
