Bloom: Prepare a 9x13-inch pan by lining it with parchment paper both directions. Allow the sides to drape over for easy handling. Set aside. In the bowl of a stand mixer, add ¼ cup of filtered water and sprinkle gelatin over the water to "bloom". Whisk to combine and set aside.
Heat: In a thick-bottom saucepan over medium heat, heat remaining water (¼ cup), honey, and salt together. Bring to a simmer and reduce heat to medium-low. Continue to simmer the honey mixture over low heat for approximately 12 minutes. Watch the honey mixture carefully so it remains contained.
Whisk: Assemble the stand mixer with a whisk attachment and position the bowl with bloomed gelatin. Turn the mixer on low setting, breaking up the gelatin. Gently, pour the hot honey mixture in a thin stream, ensuring it pours down the sides of the bowl and not directly into the gelatin.
Beat: Gradually turn mixer to high setting and continue whipping until mixture has increased in volume and is thick and glossy and stiff peaks form. (approx. 10-15 minutes) Add vanilla powder, if using.
Set: Transfer marshmallow fluff to the prepared pan and spread evenly across with spatula. Metal icing spatula works best for these healthy marshmallows. Set aside at room temperature for at least 4 hours but overnight is best.
Cut: Dust the top of the marshmallows with arrowroot. Remove the marshmallow by lifting the parchment paper flaps on the sides and transfer to a large cutting board. Carefully, remove paper from marshmallow edges and coat the edges with more arrowroot for easier handling. It should release easily. Flip over the marshmallow and sprinkle the bottom side with arrowroot. Cut to desired size. Gently toss all marshmallow pieces in loose arrowroot powder.

Notes
Storage: Store marshmallows in an airtight container at room temperature for a up to 4 days then transfer them to the refrigerator for up to 3 weeks. To freeze: Transfer them to a freezer-safe container or large ziplock bag and remove as much air as possible to avoid freezer burn. No need to thaw before using. Just add to your recipe from freezer and enjoy!Helpful tips:
Use a candy thermometer - Marshmallows are candy, so it's fitting to use a candy thermometer and cook the honey mixture until it reaches 240°F. Or just be observant and follow the cues as mentioned in the recipe directions.
Grease the knife - You may want to grease your sharp knife or pizza cutter with a neutral oil like avocado oil to allow for easier cutting.
Make mini marshmallows - Use a baking sheet with a large surface area. Spread out the marshmallow fluff as evenly as you can. After marshmallow sets, cut into smaller pieces.
Extra sweetness - Add a bit of powdered sugar into the arrowroot powder for the dusting.
Coat with starch well - To ensure that all pieces are efficiently dusted with arrowroot starch, add them a ziplock bag with the starch, seal, and shake. Remove excess starch with a fine mesh strainer.
