1 10 1/2 ounce bag mini marshmallows
1/4 cup (1/2 stick) butter
Green food coloring
4 1/2 cups cornflake cereal
Jumbo red nonpareils
Light corn syrup
Red sour balls
Stir marshmallows and butter in a large saucepan over low heat until melted and smooth. Remove from heat and tint with 5 or 6 drops of food coloring. Gently stir in cornflakes.
Scoop 1/3 cupfuls of the mixture and drop into 6 piles on each baking sheet. Let cool 5 minutes. Spray fingers with nonstick cooking spray and shape each pile into a wreath, gently compressing the flakes together. Refrigerate until firm.
Decorate wreaths with nonpareils or candy balls, attaching them with a dab of corn syrup.
