Ingredients
For the Blackberry Puree:
- 2 cups or 8 oz or 250 grams blackberries
- 1/2 cup or 100 grams granulated sugar
- 1 Tbsp fresh lemon juice
For the Marshmallow Mixture:
- 1 egg white (room temperature)
- 1/3 cup or 75 ml water
- 1 cup or 200 grams sugar
- 2 tsp or 5 grams agar agar
For Finishing:
- Powdered sugar to dust
Directions
Step 1: Prepare the Blackberry Puree
Begin by making the blackberry puree, which will infuse your marshmallows with that distinct fruity flavor. In a medium saucepan, combine the blackberries, 1/2 cup sugar, and lemon juice. Bring this mixture to a simmer over medium heat. Use a spatula to mash the berries and let the mixture simmer uncovered for about 10 minutes.
Once done, strain the mixture through a fine sieve, pressing on the solids to extract as much liquid as possible. Be sure to scrape the back of the sieve to ensure you have 1/2 cup or 125 grams of puree. Chill the puree over an ice bath until it is completely cooled.
Step 2: Whip the Egg White and Blackberry Mixture
Once the puree is chilled and slightly thickened, combine it with the egg white in the bowl of a stand mixer fitted with a whisk attachment. Beat on high speed for 8-10 minutes, or until the mixture forms thick and stiff peaks.
Step 3: Create the Agar Syrup
In a medium saucepan, whisk together 1/3 cup water, 2 tsp agar agar, and 1 cup sugar. Place the saucepan over medium heat and bring the mixture to a boil. Then, reduce the heat to a low boil and cook for 5 minutes, whisking constantly. The syrup should thicken and pour from a spoon without dribbling. Once ready, remove it from the heat.
Step 4: Combine and Pipe
With the mixer on the lowest speed, carefully pour the hot agar syrup into the whipped blackberry mixture in a thin stream. Avoid getting the syrup on the whisk and bowl. Once all the syrup is incorporated, scrape down the bowl and continue beating on high speed for another 2-3 minutes until stiff peaks form.
Immediately transfer the mixture to a piping bag fitted with a Wilton 1M large open star tip. Pipe the mixture into rose shapes onto a parchment-lined baking sheet, ensuring the roses are even in width and size.
Step 5: Allow to Set and Finish
Let the piped marshmallows stand in a draft-free, low humidity, room temperature area (around 70˚F). Allow them to set uncovered for 6-12 hours, or overnight. The marshmallows will form a glossy film on top and should come off the parchment easily. Once set, match two halves together and roll the sandwiched marshmallows in powdered sugar.

Equipment
Method
- In a medium saucepan, bring blackberries, 1/2 cup sugar and 1 Tbsp lemon juice to a simmer. Mash berries and simmer uncovered 10 min then strain through a fine sieve, pressing on the solids with a spatula. Scrape off the back of the sieve to ensure you have 1/2 cup or 125 grams of puree. Chill the puree over an ice bath until cooled.
- Once puree is fully chilled and slightly thickened, combine it with 1 egg white in the bowl of a stand mixer fitted with whisk attachment. Beat on 8-10 min on high speed or until mixture is thick and stiff peaks form. While the blackberry/egg white mixture is going, proceed with step 3.
- In a medium sauce pan, stir together 1/3 cup water, 2 tsp agar agar and 1 cup sugar. Place over medium heat, bring to a boil then reduce heat to a low boil and cook 5 minutes, whisking constantly until syrup has thickened and pours from a spoon without dribbling. Remove from heat.
- With the mixer on the LOWEST speed, and as soon as agar syrup is off the stove, immediately pour it in a thin stream into whipped blackberry mixture. Avoid getting syrup on whisk and bowl. Once syrup is in, scrape down the bowl and beat another 2-3 min on high speed until stiff peaks form.
- Right away, transfer mixture to a piping bag fitted with a Wilton 1M large open star tip and pipe roses onto parchment-lined baking sheet, keeping the roses even in width/size.
- Let homemade marshmallows stand in a draft free, low humidity, room temperature area (70˚F), uncovered for 6-12 hours, or overnight. Marshmallows will form a glossy film on top and will come off the parchment fairly easily. Once set, match 2 halves together then roll sandwiched marshmallows in powdered sugar.
