Ingredients:

Blackberry Puree:

2 cups blackberries
1/2 cup sugar
1 Tbsp lemon juice
1 egg white, room temperature

Agar Agar Syrup:

1/3 cup water
1 cup sugar
2 tsp agar agar
Powdered Sugar (to dust)

1. In a medium saucepan, bring blackberries, 1/2 cup sugar and 1 Tbsp lemon juice to a simmer. Mash berries (a potato masher works great!) and simmer uncovered 10 min then strain through fine sieve, pressing on solids with a spatula. Scrape the back of the sieve to get 1/2 cup of puree. Chill the puree over an ice bath until cooled.

2. Once puree is chilled and slightly thickened, combine it with 1 egg white in the bowl of a stand mixer fitted with whisk. Beat 8-10 min on high speed or until thick and stiff peaks form. While the blackberry/egg white mixture is whipping, proceed with step 3.

3. In a medium sauce pan, combine 1/3 cup water, 2 tsp agar agar and 1 cup sugar. Place over medium heat, bring to boil then reduce heat to a low boil and cook 5 min, whisking constantly until syrup has thickened and pours from a spoon without dribbling. Remove from heat.

4. With mixer on the LOWEST speed, and as soon as agar syrup is off the stove, immediately pour it in a thin stream into the whipped blackberry mixture. Avoid getting syrup on whisk and bowl. Scrape down the bowl and beat another 2-3 minutes on high speed until stiff peaks form.

5. While everything is still nice and warm, transfer your mixture to a piping bag and pipe onto a parchment lined baking sheet. You can use whatever type of tip you like, but I would stick to larger ones.

6. Let stand in a draft free, low humidity, room, uncovered 6-12 hours, or overnight. Marshmallows will form a glossy film on top and will come off the parchment fairly easily, then match 2 halves together and roll sandwiched marshmallows in powdered sugar. I had to leave mine overnight.

Overall this was a pretty simple recipe. Definitely not quick as it took 2 days to make, but they’re so delicious and the fresh blackberries are amazing. They just melt in your mouth..a little too easily so make sure you share them with friends.
