How to Make It
Make the brioche waffle. Mix the ingredients from warm water through 1 cup plus 3 tablespoons all-purpose flour in a stand mixer until incorporated. Let the flour mixture stand for 30 minutes.
Sift together dry ingredients from ¼ cup sugar through 5 cups all-purpose flour. Using hook attachment, alternate adding eggs and flour mix. Once incorporated, mix on medium for 8 minutes.
Coat cubed butter in flour and add butter to dough gradually on medium speed. Once added, mix for 6 more minutes.
Cover dough with a moist towel and let rest for 1 hour.
Put 1 cup dough in waffle maker until crispy on the outside, about 5 minutes.
Make the espresso maple syrup. Toast espresso beans over medium heat until fragrant, and soak in maple syrup overnight.
Make the orange compote. With a knife, peel oranges separating the flesh from the skin. Juice the orange flesh and set aside. Put the skin in a pot and cover with cold water. Bring to a boil and strain. Repeat twice to remove the bitterness. Cover peels with simple syrup and bring to a simmer and then strain Brunoise orange peel and put back into a pot. Cover the orange peels with the juice and bring to a simmer. Add agar agar and mix until incorporated. Season with salt and cool.
