Homemade Marshmallows

I like making candy. I never really thought marshmallows were candy until I made them, but now I know they are. Making them involves cooking sugar and corn syrup to the “soft ball” stage, and anything that involves cooking sugar and using a thermometer is candy to me. The result is just very different than some candies we’re used to!

At first I thought making these would be hard. Plus I’ve never used gelatin before, but making marshmallows is surprisingly easy and very fast (except for the 4-hour waiting time while they set). Try it at your own risk – you’ll want to make them all the time. My favorite way to eat them is in hot chocolate. You can also add them to your ice cream, melt them on top of brownies, or make s’mores…the possibilities are endless. Did I mention they taste better than store bought ones?

I know I was successful in making these because when I tasted the marshmallows before hardening (yes, I licked the bowl. Is that bad?) the first thing I thought was, “Wow, this tastes like marshmallow!”

I actually searched a lot of recipes before trying this one, and am definitely eager to try out some different ones. The main difference between all these recipes is egg whites. I chose this recipe without them for two reasons: it was the first hit on Google when I searched for “marshmallow recipe” and it’s Alton Brown’s recipe.

Ingredients:

  • 2 envelopes (kosher!) fish gelatin*
  • 1 1/2 cups sugar (oops)
  • 1 cup corn syrup (or simple syrup with 1/4 teaspoon cream of tartar – this is what I use instead of corn syrup)
  • 1/4 teaspoon kosher salt
  • 1 teaspoon vanilla extract
  • 1/4 cup powdered sugar
  • 1/4 cup corn starch
  • Cooking spray/unflavored oil

(The recipe calls for three packets. I did some research and found out that each envelope of the unkosher variety has a tablespoon of powder. I measured the kosher gelatin envelopes and each had 1 1/2 tablespoons. Perfect, because that’s how many come in a box.)

  • 1 cup cold water, divided

Directions:

1. Dissolve the gelatin in 1/2 cup of water in the bowl of a stand mixer with the whisk attachment.

2. In a saucepan, combine the rest of the water, sugar, corn syrup, and salt and place over medium heat with the lid on. Cook for four minutes.

3. Uncover and cook for another eight minutes, until a thermometer reads 240 degrees. Remove from heat immediately!

4. Turn the mixer on low and slowly pour the sugar mixture into the gelatin. Turn heat to high (I had to first go to medium for a minute and then increase to high because it was very splashy) and whip for another 12-15 minutes, until the mixture is light and fluffy. Add the vanilla (here I stopped the mixer to scrape down the sides) and whip another minute.

5. While the mixer is whipping, combine the powdered sugar and corn starch. Spray a 9×13** baking dish and sprinkle it with the mixture.

6. Pour the mixture onto the baking dish, flattening out with a greased spatula. Sprinkle the top with the powdered sugar and allow to rest, uncovered, for at least four hours.

7. Transfer the marshmallow sheet to a cutting board and cut into even squares. This was not as hard as I thought it would be. I pulled up at one end of the marshmallow and the rest came out pretty easily. Coating the baking dish is very important!

**So, I just realized that I made a teeny mistake. I didn’t put enough sugar! My mixture was so thin when i spread it on the baking dish – that’s probably why. They still taste like marshmallows, I just didn’t get as much as I thought. With only 1/2 cup of sugar, you should probably use a smaller baking dish. With the full amount, 9×13 should work.

    Great site! I agree homemade marshmallows are so much better than store bought. Marshmallows are my favorite thing to make, especially flavored ones. (there are several recipes on my blog if you are interested) I am happy to see that they work with fish gelatin. I have use Kolatin(kosher animal based gelatin) but I know that fish gelatin is sometimes easier to find.

    Will definitely try this. Attempted – using flavorless KoJel – to follow Molly Wizenberg’s instructions in Bon Appetit magazine about a year ago. Disaster. Made a marshmallow flavored mess. It didn’t set up. It remained a mush. So, it was back to the Elyon bagged stuff for the hot chocolate…

    During steps 2 & 3 do I stir any, or just let it boil? I’m trying to make these for my messianic friends, who have been buying theirs over seas for years now.

    I’m 17 and I’ve been making candies for a few weeks now and I have only had homemade marshmallows once 10yrs. ago and I loved them!

      just let it boil. stirring may cause crystallization, which can ruin it!

      definitely don’t stir. just let it boil – stirring can cause crystallization, which will ruin your marshmallows! 
      and good for you! homemade candies are so fun and much more delicious than store bought ones :)

    I made these with the full amount of sugar and they came out pretty good. I forgot the vanilla, but they still taste fine. Also, I ran out of light corn syrup so I figured dark corn syrup would be OK – and it was, but it really does affect the final color of the marshmallow! (it’s got a slight brown tinge, though most of the brown color was beat away by whipping all that air in). They are a pain to cut though – even using a pizza cutter like AB suggests!

    Also, thanks for the gelatin packets tip!
