Preheat oven to 400*F.
Score diagonal parallel lines about 1/4 inch deep, with paring knife, on the inside of squash flesh. Then score more parallel lines, crossing over first lines creating crosshatch pattern.
Arrange squash halves on parchment lined baking sheet. Brush with orange juice and sprinkle with salt.
Roast for 40 minutes.
While squash bakes, place rest of ingredients into a small skillet over medium heat for about 3 minutes or until sugar dissolves.
Remove squash from oven after 40 minutes, and pour off any liquid. Brush with glaze.
Return to oven and bake another 20 minutes or until tender and browned.
Remove from oven, brush any glaze from pan over squashes and sprinkle with a little more flaked salt. Serve warm.
