Zephyr is a type of Russian homemade marshmallows recipe. These tasty confections are fluffy and literally just melt in your mouth. Learn how to make these homemade marshmallows with the easy video tutorial.
I have been working on perfecting this recipe for some time and these have the right fluffy consistency using real ingredients (no jell-o needed), and they have intense blackberry-lemon flavor. P.S. that beautiful pinky-purple hue is all natural from fresh blackberries and makes these completely irresistible!
The closest thing I could compare zephyr to are gourmet marshmallows. These are lightyears better than store-bought marshmallows and are stunning on party dessert tables. Think: showers, birthdays, tea parties, etc. Zephyr is the first thing people eye on a dessert table because it’s just so pretty!
This blackberry-leon zephir recipe was modified from Air Cake on youtube.

This recipe is simple, but it is important to follow the process and have precise measurements. I have included all of my best tips to make sure you are successful the first time and every time!
*Watch our easy video tutorial on how to measure correctly

Ingredients for Blackberry Puree:
2 cups (or 8 oz or 250 grams) blackberries
1/2 cup (100 grams) granulated sugar
1 Tbsp fresh lemon juice
1 egg white, room temperature
For the Agar Agar Syrup:
1/3 cup (75 ml) water
1 cup (200 grams) sugar
2 tsp (5 grams) agar agar*
Powdered Sugar to dust

*Agar agar us a plant based thickener that works similarly to traditional unflavored pork-derived gelatin. It is kosher-friendly and doesn’t add any aroma or flavor especially when heated which is awesome!! It is available in natural and health-food stores like Rosauers, Whole foods and is reasonably priced on Amazon.
How to Make Homemade Marshmallows (Zephyr):
1. 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 fine sieve, pressing on solids with a spatula. Scrape the back of the sieve to get 1/2 cup or 125 grams 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. Right away, transfer to a piping bag fitted with a Wilton 1M large open star tip and pipe roses onto parchment-lined baking sheet, keeping them even in width/size.

6. Let stand in a draft free, low humidity, room temperature (70˚F) area, 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.

Notes
If you make this recipe, I’d love to see pics of your creations on Instagram, Facebook and Twitter! Hashtag them #natashaskitchen
Regarding the use of raw egg whites: Always use eggs that have a whole, un-cracked shell from a trustworthy source. This method is similar to an Italian Buttercream where adding the hot syrup partially tempers the egg white, but if you want to take extra caution especially if pregnant or elderly, you can try using pasteurized egg whites, although from my research, it may take longer to beat the mixture if egg white is pasteurized.

Natasha, anyway to make them white and still have a fruitie flavor?:)
I made these last week and they were yummy!! Just trying to make some white ones for a wedding!
Maybe with apple puree but it still wouldn’t be completely white. I haven’t come across any fruity flavored ones that were white. Maybe someone else has some insight into this? Thanks in advance! 🙂
I was wondering if I could use plain gelatin instead of the agar?
Lisa, the recipe requires agar agar and will not work with gelatin.
Natasha thank you for this wonderful recipe, I made these with strawberries instead of blackberries and they turned out So Goood! 😉
YAY! I’m glad to hear the recipe works well with other fruits! Thanks for sharing your review with other readers Katie!
Hi Natasha, can i use strawberry for this recipe ??
I haven’t tried it myself but I have had readers report great results substituting with strawberries.
Natasha, big thank u for the best Zeffir, I made before using other recepies didn’t turn that good. I tried u recipe today & turned very well plus not a big porshion for family of 4, love it! Big thanks for u hard work & an amazing recepies I use u site everyday ! God bless!
I’m glad to hear everyone loves recipe Oksana! Thanks for following and sharing your thoughtful review!
Oh and also, the recipe calls for 2 cups or 8oz blackberries. Is it 8oz total or 2 8oz containers?
Hi Sveta – Mine cake in 6 oz containers so I used 1 1/2 containers. If you put it into a measuring cup, it is 2 cups of berries. I’ll clarify in the recipe.
Hi Natasha,
Can I use hand mixer for this recipe, since that’s all I have?
Hi Sveta, yes. Make sure you check the notes at the bottom of the print-friendly.
Thank you
I make it but it’s still wet after 12 hours. I’m in Viet Nam (Asian) and room temperature is between 35 – 38 oC. May I have to put it in fridge (15 oC)? But after that, how can I storage it?
Hi Emma, I’m not sure since the refrigerator is not idea for these due to moisture in the refrigerator and other food smells. 35-38˚C is also very warm for these. Wow it is hot where you live!! Is it also very humid? These will have a hard time setting properly in a very humid climate. I think if it was dry and warm, that would work better than humid and warm…
I made my zephyr and they looked perfect, but they were still wet after 12 hours..and I live in Oregon, so it’s somewhat humid right now but not entirely..what else can be a factor?
Hi Kseniya, humidity may be the culprit but some other things to consider: it may be due to undercooking the agar mixture – I cook at a low boil for the full 5 minutes for it to thicken. Also, be sure not to add more than 1/2 cup of your fruit syrup and make sure it is fully cooled and no longer warm to the touch. I hope that helps! 🙂
Hi, i tried it and came nice only issue i am experiencing is even afyer ober night they are still not like marshmellow. I gollowed recipe pretty thourouly.
Hi Tim, did you use agar agar and no more than 1/2 cup of fruit puree? The measurements should be precise in this recipe to get the right consistency. They don’t get as dry as store-bought marshmallows (they are a slightly more moist inside) and the outside should no longer stick to your finger tips after letting them rest overnight. Also, did you allow the agar syrup to cook at a low boil for 5 minutes – the timing of this is because agar agar needs to reach a certain temperature to work properly. I sure hope that helps! 🙂
I made mine with blueberries today, they turned out just as nice but they were more of a deeper purple than the blackberry ones and less of a blue like you would think. Also instead of putting the blueberry mixture through a sieve I put it in a mini food processor & pulsed it really well. This turned out better than putting it through a sieve because blueberry seeds are much smaller than blackberry ones plus I wasn’t getting much syrup through the sieve process. You can also skip the ice water bath after pulsing it because it’s thick enough ( or at least mine was). Everything else I did the same. Just one more tip, once your agar agar mixture is thick enough IMMEDIATELY remove from the heat and pour into mixing bowl, I walked away for 30 seconds and came back it was ruined had to trash it. Thanks for such a delicious recipe!
Thank you so much for sharing your tips with us Tanya. It’s great to know that it works with blueberry – there were a couple other people that asked about that specifically and I wasn’t sure. Thanks again!! 🙂
Hi Natasha!
May I ask what kind of whisker you are using here? Looks very comfortable …) ?
Thanks!
Hi Ana, the whisk I’m using is a Zwilling whisk and I do love it! 🙂
Thanks! :):)
My pleasure Ana 🙂
Does it really take 7 hours for preparation?
Hi Elona, that time is just letting the marshmallows rest. It’s not really preparation time at all.
How far ahead can you make them? I mean, can they sit for a couple days and still taste the same?
And by the way, I love all your recipes! This is my go to site.
Hi Irina, I have made them a couple of days in advance and they were still great 😉
Hello, can I make this recipe with strawberries?
please
I haven’t tried that but I think it could work. You may need to cook the strawberry puree a little longer so it thickens since strawberry juice tends to be a little more watery and be sure not to add more than 1/2 cup of puree. Let me know if you try it 🙂
Wow, it looks so beautiful!!! My 5 year old daughter wants this pretty pink flowers for her birthday:)
They taste as good as they look Jessi! Please let me know what you think of the recipe if you decide to make these!
Hi Natasha,
Can i use it without egg white?
Hi Steven, I haven’t tried any other substitution as this is traditionally made with egg white. I can’t think of anything else that will cause it to rise properly like the egg white.
These are the prettiest marshmallows I’ve ever seen, Natasha! Love the recipe!
Thank you, aren’t they gorgeous!? They tastes as good as they look too Julia!
I buy agar agar at Vietnamese store in my town. It will say “agar-agar” on a package on English or you can ask any workers there and explain what are you looking for and they will show you .
Hi Anna, thank you for sharing!
Hello Natasha, could I use gelatin powder instead of the agar?
Thank you,
Ella
Hi Ella, I haven’t tried that replacement since this recipe is typically made with agar agar powder. One of my readers reported using gelatin powder but she said they didn’t turn out quite right so I think there needs to be some modifications to try using regular unflavored gelatin powder but without testing it myself, I really can’t say for sure.
Thank-you for the perfect zephyr recipe! One suggestion- please use either ‘syrup’ or ‘purée’ consistently when talking about the sweet blackberry mixture, I got confused multiple times regarding what to put in the mixer, whether you wanted me to use the syrup= drained juice with sugar or the purée = leftover mushy stuff after draining syrup.
*thankful for the backup video that cleared up my misunderstanding 🙂
Thank you so much for catching that!! Fixed!! 🙂
