How to Make Blackberry Mousse with Rosemary Crumble

  1. Combine the blackberries, sugar, lemon juice, lemon zest, cornstarch, and water in a saucepan. Stir well, then place over medium heat. Bring to a boil and simmer for 10 minutes until the mixture thickens. Strain through a fine-mesh strainer into a bowl, cover with cling film, and let cool to room temperature before refrigerating.

  2. Beat together the egg yolks and honey in a small bowl. In a separate large bowl, place the white chocolate chips. In a saucepan, pour in the milk and vanilla paste, stir, and then place over medium heat. Bring to a boil, then simmer for 1 minute. Remove from heat and whisk in the gelatine until dissolved. Pour this mixture over the egg yolks while whisking continuously to achieve a smooth texture. Return the mixture to the saucepan and cook over low heat for 4-6 minutes, stirring constantly until it thickens slightly and coats the back of a spoon.

  3. Pour the creamy mixture over the white chocolate in the bowl. Allow it to sit for 5 minutes. Stir gently until smooth. In another bowl, beat the whipping cream until stiff peaks form. Carefully fold the whipped cream into the chocolate mixture, then add half of the cooled blackberry marmalade, and gently fold until well combined. Divide the mousse into four glasses or bowls, cover with cling film, and refrigerate for 2-3 hours or overnight.

  4. Preheat your fan-assisted oven to 170°C/340°F or a regular oven to 180°C/350°F. Line a baking sheet with parchment paper. In a bowl, combine the all-purpose flour, ground almonds, and sugar. Add cubed butter, rubbing it lightly into the mixture until it resembles sand. Knead just to combine, then spread the mixture on the prepared baking sheet and bake for 20-25 minutes until golden brown and crunchy. Allow to cool and store in an airtight container until ready to use.

  5. Serve the mousse chilled by adding a tablespoon of homemade blackberry marmalade on top, then sprinkle with the rosemary crumble for a delightful crunch!

Optional: Garnish with a few fresh blackberries for an elegant touch.

How to Store and Freeze Blackberry Mousse with Rosemary Crumble

Fridge: Keep the chilled blackberry mousse covered in cling film for up to 3 days to maintain its creamy texture and flavors.

Freezer: For longer storage, freeze the mousse (without the rosemary crumble) in airtight containers for up to 1 month. Thaw overnight in the fridge before serving.

Crumble: Store the rosemary crumble in an airtight container at room temperature for up to 1 week to preserve its crunchiness.

Reheating: While the mousse should not be reheated, if you have leftover crumble, you can lightly warm it in the oven for a few minutes to refresh its texture.

Expert Tips for Blackberry Mousse with Rosemary Crumble

  • Choosing Blackberries: Opt for ripe, fresh blackberries when possible; their flavor is more intense and they truly enhance the blackberry mousse.

  • Gelatine Precision: Be cautious with the gelatine measurement; too much can make the mousse overly firm, while too little will leave it too loose.

  • Whipping Cream Secret: Ensure your whipping cream is chilled before whipping; this results in better volume and stability when folding into the mousse.

  • Mind the Egg Yolks: Whisk the egg yolks and honey well to prevent curdling when mixed with the hot cream mixture—this keeps the mousse silky smooth.

  • Crumble Texture: Don’t over-knead your rosemary crumble mixture; a light touch creates a perfect crunchy texture that complements the creamy mousse beautifully.

Remember, patience is key, as chilling the blackberry mousse with rosemary crumble will yield the best results!

Blackberry Mousse with Rosemary Crumble Recipe FAQs

How do I choose ripe blackberries?
Absolutely! When selecting blackberries, look for ones that are deep black in color, firm to the touch, and plump. Avoid any with dark spots all over, as those might be overripe or spoiled. Fresh blackberries are usually available in the summer, but you can use frozen ones year-round for convenience.

What is the best way to store leftover blackberry mousse?
Very simple! Cover the chilled blackberry mousse tightly with cling film or transfer it to an airtight container. It will stay fresh in the fridge for up to 3 days. Just make sure to store the rosemary crumble separately to maintain its crunchy texture!

Can I freeze blackberry mousse, and how?
Yes, you can! To freeze the mousse, pour it into airtight containers, leaving some space at the top for expansion. It will keep well for up to 1 month. When you’re ready, thaw it overnight in the fridge. Note that the mousse’s texture may change slightly, but it will still taste delightful!

What should I do if my mousse doesn’t set properly?
If your mousse doesn’t set, it might be due to insufficient gelatine or not incorporating it correctly. To troubleshoot, ensure you follow the gelatine’s instructions accurately and allow it to bloom properly before adding it to your warm mixture. If it still doesn’t set, you can mix in extra softened gelatine, following the same blooming method.

Is this recipe suitable for those with allergies?
Be mindful! This recipe contains eggs, dairy, and nuts. If you’re cooking for someone with allergies, be sure to substitute the dairy with suitable alternatives, like coconut cream, and skip the ground almonds. Always check ingredient labels to confirm that no hidden allergens are present!

How long can I store the rosemary crumble?
Absolutely! The rosemary crumble is best stored in an airtight container at room temperature for up to 1 week. Keeping it away from moisture will ensure it retains its delightful crunch, ready to sprinkle over your mousse when you’re ready to serve!
