I used this recipe, omitted the extracts and replaced them with 2 teaspoons vanilla bean paste
• royal icing: divided and tinted with Americolor Leaf Green, Terracotta, and Watermelon
Use #2 tips to outline the cactus and planter in green and terracotta.
Thin both the green and terracotta icing with water, a bit at a time, until a ribbon of icing dropped back into the bowl disappears in a count of 2-3 seconds.
Using the piping consistency royal icing, add detail to the planter with terracotta icing.
I would say if you love watermelon we can't be friends, but I'm married to a watermelon-lover, soooooo....
