Episode notes
Summer Versus Winter Is About Timing
- The summer vs. winter squash distinction hinges on harvest timing, not species.
- Summer squash is eaten immature (about 6–8 days post-pollination); winter squash is eaten at full physiological maturity (~60 days).
Gourd Versus Squash Distinction
- The gourd vs. squash divide is debated, but a practical rule is gourds are hard-shelled ornamentals and squash are for eating.
- Gourds were domesticated very early and have long archaeological history.
Canned Pumpkin Is Usually Squash
- Canned "pumpkin" is often Hubbard or butternut-type squash, not jack-o'-lantern pumpkin.
- Use labeled varieties like Hubbard or butternut when you want good eating quality in recipes.
