Strawberry reduction is super easy to make. In a nutshell, you puree strawberries, add a little lemon, salt, and maybe some sugar, and reduce by half over low heat. I typically use it for my strawberry cake recipe, strawberry buttercream, or as a cake filling so I like mine to be a bit thicker.

Whats The Difference Between A Puree and A Reduction?

Strawberry reduction and strawberry puree are not the same thing. A puree is just blended strawberries and is mostly water. For baking we typically need the strawberry flavor to be more intense.

To make your strawberry puree thicker, you're going to want to simmer it for a few minutes. Simmering the mixture reduces the amount of moisture that is in the puree allowing for a stronger strawberry flavor with less liquid. 

The best thing about making a reduced strawberry puree is that it keeps all the flavor of the strawberries without adding extra moisture.

Strawberry Reduction Ingredients

I prefer to use frozen strawberries because frozen fruit is generally picked at the peak of freshness and then frozen. You get the most flavor in frozen strawberries.

If strawberries are in season though and you need to use them up, making puree is a great option. You can freeze leftover puree and defrost as you need it. If you're super talented and know how to can, you can make canned puree. This is definitely on my to-learn list.

When buying fresh strawberries, choose brightly colored, shiny berries that are dry, firm, and plump. They should still have fresh-looking green caps attached. Avoid soft, dull-looking, or shriveled berries. Since strawberries do not ripen after being picked, avoid berries that are partly white as that means they are unripe

How to make a strawberry reduction in 5 easy steps

  1. Defrost your strawberries or chop up your fresh strawberries.
  2. Blend your strawberries in a blender or give them a quick blend using an immersion blender. close up of strawberries in a blender
  3. Add the blended strawberries, sugar, lemon zest, and salt and bring it all to a simmer on medium heat.close up of strawberry reduction ingredients in a saucepan
  4. Reduce the heat to medium-low so it's just barely bubbling and allow the mixture to reduce (40-60 minutes). Stir occasionally to prevent burning. The reduction should look like tomato sauce, not watery. Close up of strawberry reduction on a spoon
  5. Let the strawberry reduction cool before using.

How to store the leftover strawberry reduction

You can store leftover strawberry reduction in the fridge for two days or you can freeze it up to 6 months. Fresh strawberries are very prone to mold so be sure to only leave cakes with fresh fruit fillings at room temperature for no more than 2 hours. Cakes with fresh fruit filling can be refrigerated for two days before consumption.

    hi, when I made this reduction the color was not the bright tomato sauce red you had and was more of a soft brown red. I used a lb of fresh strawberries and blended them as instructed, it was foamy and stayed foaming for a while. it didn't get the bright red color as yours. what did I did wrong? strawberries were in season

      It could just be the type of strawberries you are using. Different strawberries will produce different results.

    I want a seedless reduction. Where in the process should I strain the strawberries?

      I would blend the strawberries ahead of time, strain, then cook them.
