Start by supreming two of the blood oranges. To supreme a blood orange, cut off the top and bottom just until the pulp is exposed. Stand the blood orange up on one of the flat ends. Working from top to bottom, cut away the the peel and pith, following the curve of the fruit. Slice out each orange segment by cutting in towards the center of the fruit along the connective membranes. The segment should fall out on its own, but you can use your knife to help if needed. Repeat with remaining orange. Set aside segments.
Squeeze the juice from the remaining membrane into measuring cup. You will need a total of 7 tablespoons blood orange juice for the sauce. Juice the remaining blood oranges until you have the 7 tablespoons. Pour blood orange juice into a small saucepan. Add lemon juice, maple syrup and a small pinch of kosher salt, stirring to combine. Bring mixture to a light simmer and cook until reduced to 3 tablespoons of thick syrup (20 - 25 minutes). Pour the syrup through a fine mesh strainer into a clean bowl, let cool then stir in orange-flower water.
Pull apart the radicchio leaves then tear them large pieces. Add them to a large mixing bowl with 2 handfulls of red baby lettuce leaves. Toss gently with extra virgin olive oil, a small pinch of kosher salt and several turns of black pepper.
To serve, divide ricotta cheese between two salad plates. Next add the radicchio, baby lettuce leaves and blood orange segments. Top with toasted pine nuts, pomegranate seeds and red micro greens. Finish with a drizzle of the blood orange syrup.
