Pro Tips
- Store whole, unwashed squash on shelves with space between fruits
- Keep temperature between 50-60°F (10-15°C) with 50-70% humidity

Origin & Heritage
History
Hubbard squash was developed in the 1850s by American gardener James Gregory in Marblehead, Massachusetts. The variety was named after Elizabeth Hubbard, the wife of a local sea captain, who provided seeds from her garden. It represents a culmination of selective breeding from wild Cucurbita maxima varieties indigenous to Central America.
Cultural Significance
Hubbard squash became integral to New England and North American autumn traditions, particularly associated with Thanksgiving and fall harvest celebrations. Its ability to store through winter made it a crucial survival food for early American settlers and remains symbolically linked to harvest abundance and seasonal cooking.
The Science
Understanding the key chemical compounds helps explain why hubbard squash pairs well with certain ingredients.
Compound responsible for orange-yellow pigmentation; converts to vitamin A in the body and provides subtle sweet undertones
Citral terpene contributing fresh, slightly citrusy notes when squash is freshly cut or cooked
Volatile aldehyde creating green, grassy aromatic notes in raw squash
Natural sugars concentrated during ripening and further enhanced through roasting via the Maillard reaction
Floral compound found in trace amounts contributing subtle herbal and slightly spicy aromatic quality
