Any squash will work here, though heartier versions like Kabocha, Delicata, and Red Kuri will withstand the time spent braising while holding their shape. If you don’t have a sweet tooth, the charred date topping may not be a necessary addition for you, but I really like the pop of sweetness. Charring them brings out what are almost toasted marshmallow-y flavors, which might sound weird, but really hit the spot. Do you!
