A visit to the mercado in any city or town in Mexico is an essential cultural experience for any traveler. Here, at the central market in Mérida, a local Maya woman has, amongst her offerings, calabacita “local” as they refer to it there. It’s the young, soft-skinned, Calabaza Castilla, and delicious sliced and roasted. Use it similarly to what is commonly called “Acorn squash” in the US and Canada. The skins become tougher, and seeds form a harder casing as they get larger so those under 3in (7-8cm) diameter are most tender.
