Ingredient Notes
This recipe is on my long list of things to do with leftover egg whites. This Blueberry Mousse recipe is one of my favourites: so quick and easy to make, and you can make it with virtually any frozen fruit or berries you have in your freezer. I've tried it with blackberries and cherries as well!

- frozen blueberries: and if you have some left over, make some delicious Sourdough Blueberry Pancakes (Made With Discard).
- caster sugar.
- large egg white: 1 large egg white weighs approximately 40g. Make sure it is safe to use raw egg whites in your part of the world.
- whipped cream: use double cream, also known as heavy cream (or whipping cream) and whisk it to soft peaks. This is optional and can be replaced with thick Greek yoghurt, or skipped altogether. The mousse tastes great with sweetened cream cheese or sour cream too.

Method: Blueberry Mousse in Under 10 Minutes
If you wish to serve the blueberry mousse with some cream, whisk it first in a large bowl using an electric hand mixer, or in a stand mixer fitted with a whisk attachment. You can sweeten the cream slightly and further flavour it with a dash of lemon juice.
1. Add frozen blueberries to a food processor (we are huge fans of Kenwood) and blend a rough puree. Add sugar and pulse to combine.
2. Add the egg white and blitz again until the mixture is smooth and fluffy. It will take about 2-3 minutes and the mixture will at least double in volume. You may want to stop the processor once in a while and scrape the sides down if the blueberry puree is sticking to the sides.


3. Spoon the blueberry mixture into serving glasses (here are the wine glasses we used). You can layer it with some whipped cream if you wish. Serve immediately before the blueberries start to melt and release too much water.
Recipe FAQs
It depends. You really need a strong and powerful tool with sharp blades, as we are using frozen blueberries in this recipe. Regular liquidisers and smoothie blenders may not do the job here. But what you can do, is to add a couple of spoonfuls of Greek yoghurt to the mix and make a delicious Blueberry Frozen Yoghurt. Added yoghurt introduces more moisture into the mousse and helps with the blending if your gadget isn't powerful enough to blitz frozen blueberries on its own.
This easy blueberry mousse should be served immediately. Do not leave at room temperature for more than a couple of minutes. Alternatively, you can freeze it, and serve it frozen as a refreshing summer dessert.

could I make this with fresh blueberries?

Unfortunately not, the texture of this mousse relies on super cold berries.
