This creepy edible green goo is essentially homemade lime gel frosting, which means it can be used as a fun prop for Halloween desserts and mixed drinks.
‣ 1 tablespoon water, cold ‣ 1 teaspoon cornstarch ‣ 1 cup light corn syrup ‣ 1 tablespoon lime juice ‣ 1 teaspoon lime zest ‣ 1 teaspoon green gel food coloring
To kick things off, start by creating a slurry. In a small bowl, whisk together the cold water and cornstarch, then set it nearby.
In a small saucepan, add the light corn syrup, the slurry you just made, lime juice, lime zest, and green gel food coloring. Bring the mixture to a simmer over medium heat, then cook for 30 seconds while whisking constantly.
Remove the saucepan from heat and allow the liquid to cool completely. Once cool, use the green goo in fun Halloween props like syringes or beakers.
