The hawthorn blossom is the official state flower of Missouri (and rightly so; as many as 100 varieties of hawthorn live in Missouri). The hawthorn is easy to pipe; all you'll need are white, yellow, and pink stiff consistency royal icing, petal tip #104, round tips #3 and #2, star tip #16, a glue stick, a flower nail, parchment paper squares, a Styrofoam brick to rest the nail in, and a dusting pouch filled with a 50/50 mix of cornstarch and powdered sugar. You'll notice I used a 5-petal flower template on the nail to help keep the five petals equal. Start by sticking a parchment square to the flower nail with a dab from the glue stick.
After the stamens have firmed up for a while, pipe pink dabs of icing on their ends with the #2 tip. Squeeze out a tiny dab amount of icing from the tip, and then wipe it off against the stamens (or pipe directly on them; they MUST be dry or they'll break). Now you'll know what to decorate your cupcakes with for Missouri Day (which, as I write this, is coming up; the third Wednesday in October!).
