Pine needles may be calorie-negative and unpleasant to eat, but they're very high in Vit C and available in the dead of winter. I would hardly call them inedible. You can make an oxymel to extract the vitamins & make it easier to eat.

Or brew them as a tea.

The fresh shoots don't taste all bad. Definitely bitter, but not in an unpleasant way.
