Ingredients
To create these delightful marshmallows, gather the following ingredients:
- 2 cups or 8 oz or 250 grams blackberries
- 1/2 cup (100 grams) granulated sugar
- 1 tablespoon fresh lemon juice
- 1 egg white (room temperature)
- 1/3 cup (75 ml) water
- 1 cup (200 grams) sugar
- 2 teaspoons (5 grams) agar agar*
- Powdered sugar for dusting
Instructions
Step 1: Prepare the Blackberry Puree
Simmer the Blackberries: In a medium saucepan, combine the blackberries, 1/2 cup of sugar, and 1 tablespoon of fresh lemon juice. Bring this mixture to a simmer over medium heat. Use a spatula to mash the berries as they cook, ensuring they release their juices.
Strain the Mixture: After simmering for about 10 minutes, strain the mixture through a fine sieve into a bowl, pressing on the solids with a spatula to extract as much liquid as possible. This should yield about 1/2 cup (or 125 grams) of blackberry puree.
Chill the Puree: Place the strained puree over an ice bath until it is fully cooled and slightly thickened. This will ensure that your final marshmallow mixture achieves the desired consistency.
Step 2: Whip the Egg White Mixture
Combine Ingredients: Once the blackberry puree is completely chilled, transfer it to the bowl of a stand mixer fitted with a whisk attachment. Add the room temperature egg white to the puree.
Whip to Stiff Peaks: Beat the mixture on high speed for 8-10 minutes, or until thick and stiff peaks form. This step is crucial for achieving the marshmallows’ signature airy texture.
Step 3: Prepare the Agar Syrup
Mix Ingredients: In a medium saucepan, stir together 1/3 cup of water, 2 teaspoons of agar agar, and 1 cup of sugar.
Cook the Syrup: Place the saucepan over medium heat and bring the mixture to a boil. Reduce the heat to a low boil and cook for about 5 minutes, whisking constantly until the syrup thickens and can be poured from a spoon without dribbling.
Remove from Heat: Once the syrup reaches the desired consistency, remove it from the stove immediately.
Step 4: Combine and Pipe the Mixture
Incorporate the Syrup: With the stand mixer on the lowest speed, slowly pour the agar syrup into the whipped blackberry mixture in a thin stream. Avoid getting the syrup on the whisk or the sides of the bowl.
Final Whip: After incorporating the syrup, scrape down the bowl and increase the mixer speed to high. Beat the mixture for another 2-3 minutes until stiff peaks form once again.
Pipe the Marshmallows: Transfer the mixture into a piping bag fitted with a Wilton 1M large open star tip. Pipe rose shapes onto a parchment-lined baking sheet, ensuring the roses are even in width and size.
Step 5: Set and Finish
Allow to Set: Let the piped marshmallows stand in a draft-free, low-humidity room at room temperature (around 70˚F) for 6-12 hours, or overnight. During this time, they will form a glossy film on top and be easy to remove from the parchment.
Assemble and Dust: Once set, match two marshmallow halves together, then dust them with powdered sugar to prevent sticking and add a touch of sweetness.

Homemade Marshmallows (Zephyr)
Ingredients
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 saucepan, 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.
