Sift together flour, baking powder and salt in a bowl; set aside. Using electric mixer on medium, beat butter and sugar in large bowl until creamy and light, about 2 minutes. Beat in egg yolks one at a time. Add orange juice, zest, ginger and extracts; mix thoroughly to incorporate. Add flour mixture in two additions, beating on low speed just to blend between additions. Fold in minced candied ginger. Cover bowl in plastic wrap and chill for 2 hours or overnight.
To bake, preheat oven to 350 degrees. Line baking sheets with parchment. Form dough into 1-inch balls, and place at least 1 1/2 inches apart. Use a fork to flatten each ball. Bake for 10 minutes, or until lightly browned and firm around edges.
