To make cookies: Preheat oven to 350 F. Lightly grease baking sheet.
In large bowl, stir flour, sugar, baking powder, baking soda and salt to combine.
Add olive oil, vanilla extract and almond extract. Stir until crumbly dough forms.
Add 2 tablespoons milk; stir until soft dough ball forms, adding more milk if needed.
Place dough ball on lightly floured surface. Roll out dough until 1/4-inch thick. Using jar lid or other circular object, cut out cookies; place on baking sheet. Repeat until all dough is used.
Bake 8-10 minutes; do not overbake. Set aside to cool.
To make glaze: In small bowl, stir powdered sugar, 2 tablespoons orange juice and salt until thick glaze forms. Add more juice, if needed, to thin out glaze or add more powdered sugar to thicken.
When cookies are cooled, glaze them. Top with orange slices or blood orange slices and pinch of sugar.
