They also make great replacements for ingredients for other tasty rice based squares.
Step 1: Required ingredients:
two 1/2 cups of water, separated. (each will be used for a different step)
12 ounces (by weight) sugar, approximately 1 1/2 cups by volume
1 cup light corn syrup (not the dark stuff)
1/2 teaspoon salt
1 teaspoon of the extract of your choice (mint, vanilla, almond, sheep, ect.)
confectioners' sugar (used for dusting pans and the finished marshmallows, no exact amount needed)
butter (for greasing pan)
heat proof spatula
8x13 inch pan
pizza cutter or knife
Step 2: Grease and powder pan
Sprinkle the pan with confectioners so that the butter is completely coated with the suger. This prevents the marshmallows from sticking to the pan and makes extraction much easier later. It is better to use too much confectioners sugar than too little.
Step 3: Prep and measure candy ingredients
Mix the corn syrup, sugar, salt and water in a small sauce pan and heat over medium heat. Attach the candy thermometer to the pan and stir occasionally until the mixture reaches 240 degrees F.
