One of those things you never really think about being able to make yourself. They are so creamy and soft. My husband was scraping the bowl clean and I was cleaning off the whisk. It was THAT good
From Alton Brown
~3 packages unflavored gelatin
~1 cup ice cold water, divided
~1 1/2 cups sugar
~1 cup light corn syrup
~1/4 tsp salt
~1 tsp vanilla
~1/2 cup powdered sugar
~1/2 cup cornstarch
Place 1/2 cup water and gelatin into bowl of stand mixer. Put on whisk attachment
In a small saucepan, combine the other 1/2 cup water, sugar, syrup, and salt. Put on med-high heat and cover. Cook for 3-4 minutes. Uncover and clip on a candy thermometer. Cook 7-8 minutes until it reaches 240 or "soft ball" stage. Once temperature is reached, remove immediately from heat.
Turn mixer on lowest speed and pour sugar syrup down the side of the bowl. Once added, increase speed to high. Continue to mix on high 12-15 minutes until very thick.
Add vanilla in last minute of mixing.
Meanwhile, spray 9x13 pan with nonstick spray. Sprinkle with cornstarch mix and move around to completely coat.
When ready, pour the marshmallow mix into the pan and spread around with a oiled spatula. Dust top with cornstarch mix. Reserve the rest for later.
Let sit 4 ours or overnight.
Turn marshmallows out onto a cutting board and cut into one inch squares. Lightly dust all sides with cornstarch mix and store in airtight containers up to 3 weeks
