Ingredients

Meringue

60 grams (2.10 ounces) sugar
60 grams (2.10 ounces) egg whites

Syrup

125 grams (4.40 ounces) blackberry puree
7 grams (0.25 ounces) agar
75 grams (2.65 ounces) water
180 grams (6.35 ounces) sugar

Marshmallow Sprinkling Mix

powdered sugar and cornstarch in a 1:1 ratio

Instructions

Step 1

1. Pour the blackberry puree into a saucepan. Add sugar and agar to the puree. Pour in water and place the mint sprigs. Mix everything well to avoid lumps and bring it to a boil. Continue boiling until the mixture reaches a temperature of about 95-98°C (203-208°F) and becomes stringy.

Step 2

Stir continuously to prevent sticking.

Step 3

2. While the syrup is boiling, whip egg whites with a pinch of salt in a separate bowl. Gradually add sugar and increase the speed of the mixer until you achieve a stiff, glossy meringue.

Step 4

Make sure your mixing bowl and beaters are clean and dry for the best meringue results.

Step 5

3. Remove the mint sprigs from the boiling syrup. Gradually pour the hot syrup into the meringue in a thin stream while continuing to whip at maximum speed.

Step 6

Pour the syrup slowly to avoid cooking the egg whites.

Step 7

4. Continue whisking the mixture until it becomes thick and no longer flows. Quickly mix the grapefruit pulp into the mixture by hand using a spatula to evenly distribute the pieces.

Step 8

Be gentle to maintain the airy texture of the meringue.

Step 9

5. Transfer the mixture to a pastry bag fitted with a closed star nozzle and pipe out the marshmallows onto a baking sheet. Allow them to dry and stabilize for 8 to 12 hours.

Step 10

Use a silicone mat or parchment paper for easy removal.

Step 11

6. Once dry, unite the marshmallow halves and dip them in a mixture of powdered sugar and cornstarch. Bon Appétit!

Equipment

Electric Mixer

A stand or hand mixer will do the trick here. Ensure it's powerful enough to whip egg whites into stiff peaks.

Pastry Bag with Closed Star Nozzle

This is essential for forming the beautiful shapes of your marshmallows. If you don't have a closed star nozzle, any nozzle will work, though the shapes will vary.

Saucepan

You'll need this to prepare the syrup. Choose a medium-sized one to prevent overflow when the syrup boils.

Spatula

Use this to mix the grapefruit pulp into the marshmallow mixture. Silicone spatulas are best for their flexibility and heat resistance.

Digital Thermometer

Measuring the exact temperature of your syrup is crucial to achieving the perfect "stringy thread" stage.

Variations

To make these marshmallows gluten-free and vegan, substitute the egg whites with aquafaba (the liquid from a can of chickpeas). Whip the aquafaba just like you would with egg whites until stiff peaks form.

For the blackberry syrup, replace sugar with a plant-based sweetener like coconut sugar and ensure your agar is vegetarian. Be mindful to check that all ingredients you use are certified gluten-free. These substitutes are game-changers, bringing the same delightful texture and flavor without compromising dietary choices.

Faq

  • Why are my egg whites not forming stiff peaks?

    Ensure your bowl and beaters are completely clean and grease-free. Even a small amount of fat can prevent the whites from whipping properly.

  • Can I use a hand whisk instead of an electric mixer?

    While technically yes, it's highly labor-intensive and may not achieve the desired consistency. An electric mixer is recommended.

  • How can I tell if the syrup has reached the "stringy thread" stage?

    Use a digital thermometer to ensure the syrup temperature is between 95-98°C (203 to 208°F). Alternatively, drop a small amount into cold water to see if it forms a thread.

  • My syrup crystallized! What did I do wrong?

    Ensure you're constantly stirring and avoid any sugar crystals from sticking to the sides of your saucepan. Brushing the sides with water can help.

  • Can I infuse different flavors into the marshmallows?

    Absolutely! Feel free to experiment with different fruit purees or even infuse the syrup with herbs like rosemary or basil.

  • How do I prevent the marshmallows from sticking together?

    After forming your marshmallow shapes and allowing them to dry, coat them in a mixture of powdered sugar and cornstarch to prevent sticking.
