- 3 3/4 tsp unflavored gelatin
- 1/2 C ice cold water, divided
- 3/4 C sugar
- 1/2 C light corn syrup
- 1/8 tsp kosher salt
- 1/2 tsp vanilla
- 2 Tbsp powdered sugar
- 2 Tbsp cornstarch
2. In a medium saucepan, stir together remaining 1/4 cup water, sugar, corn syrup and salt. Cover and cook at medium high heat for 2-3 minutes. Uncover, clip a candy thermometer to side of pan, and continue to cook until the mixture reaches 240°F. Remove from heat immediately upon reaching that temperature.
3. With the mixer running on low speed, slowly pour the sugar syrup down the side of the bowl into the gelatin mixture. Once all syrup has been added, increase speed to high. Continue to whisk until mixture is lukewarm and very thick, approximately 6 to 8 minutes. Add the vanilla during the last minute of mixing (if you'd like to make peppermint marshmallows, replace vanilla with peppermint extract).
4. While mixture is whisking, prepare pan. Combine powdered sugar and cornstarch in a small bowl. Lightly spray an 8x6" pan with nonstick cooking spray. Add sugar-cornstarch mixture and shake to coat the bottom and sides of the pan. Return the remaining mixture to the bowl for later use.
5. When marshmallow fluff is ready, pour the mixture into the prepared pan, using a lightly oiled spatula for spreading evenly. Dust the top with enough of the remaining sugar-cornstarch to lightly cover. Reserve the rest of the sugar-cornstarch mix. Let marshmallows sit uncovered for at least 4 hours or overnight.
6. Turn pan out onto a cutting board and cut into 1-inch squares using a pizza wheel or knife dusted with the sugar-cornstarch mix. Once cut, lightly dust all sides of each marshmallow with the remaining mixture. Can be stored in an airtight container for several weeks.
Robyn's notes: this really isn't at all difficult, it's just time-consuming and there is a lot of dish-washing that can't be put off (get those sugar syrup- and marshmallow fluff-covered items soaking in hot water right away or you'll be chipping away at them for ages!). I find it actually fairly soothing to make candy, but don't get complacent! Sugar syrup at 240°F is a burn waiting to happen if you're not paying attention! If you can get unflavored gelatin in a large canister, it's easy to measure out. Otherwise, this is 1 1/2 packets from the box. Watch me demonstrate this recipe on youtube!
**** 4 Stars: Very Good. Enjoyed by us both, I will make this frequently
