Eggs and sugar have great chemistry. Mix them together to create these sweet, crunch Halloween treats with a recipe from my upcoming book “Kitchen Science Lab for Kids: Edible Edition.“
They’ll take a few hours to bake, so plan ahead for this fun, edible science project.
Meringues are simply egg whites whipped into sugary foams. As you whip air into the mix, glue-like egg white proteins stick to the bubbles, stabilizing them to form a thick foam. The sugar you add combines with water from the eggs to form a sweet syrup.
When you bake meringue at a low temperature for a long period of time, the sugar and protein are transformed from an elastic goo to a glassy state, creating a crunch mouthful of bubbles.
Hard meringues are made using ¼ cup sugar per egg white, with a pinch of cream of tartar. Don’t skip the cream of tartar (an acid.) It helps stabilize the egg whites in the meringue.
To make Halloween Meringues, you’ll need:
3 egg whites from extra large eggs
1/8 tsp cream of tartar
¾ cup granulated sugar
1/4 tsp Vanilla
Food coloring (gel works best)
Sprinkles or dusting sugar (optional)
Stand mixer or hand mixer
2 baking sheets
Pastry bags or large plastic zipper bags with the corners cut off
Round piping tips for pastry bag, if you have them
1. Pre-heat oven to 200 degrees F.
2. Line two baking sheets with parchment paper.
3. Beat three egg whites on medium until they start to foam.
4. Add 1/8 tsp. cream of tartar and continue to beat the egg whites, increasing the speed to high.
5. When the foam gets thicker enough to form soft peaks, add 3/4 cup sugar, a tablespoon or so at a time as you beat the eggs. Add vanilla.
6. Continue beating the mixture until stiff, glossy peaks with rounded tips form. Don’t over-beat the meringue.
7. Add a round tip to the pastry or plastic bag. Fill the bag with the meringue you made.
8.Use the bag and tip to pipe half of the meringue into blobs. You can color it with food coloring before piping it, if you wish.
9. Make some colorful streaks on the meringues by using a toothpick to smear food coloring on the inside of the pastry tip before putting it in the bag and piping the meringue. A small tip can be used to create eyes for the blobs, snakes and worms, or you can use sprinkles and dusting sugar to decorate.
10. Bake the meringues for 1-2 hours, until they feel dry and let them cool.
