Pastel de Chila

There's a magic trick at the heart of this tart. A vegetable, transformed. The chila squash, a large pale gourd that looks like nothing special, becomes something extraordinary in the hands of someone who knows its secret.

The nuns figured it out centuries ago. Cook the chila, and its flesh separates into long golden strands, like threads of silk, like angel hair. Add sugar, cook it slowly, and you have doce de chila, one of Portugal's most beautiful preserves. Then fold in egg yolks, as the convents always did with their abundance of yolks, and you have something that makes people stop mid-bite and ask: what is this?

Avó Leonor called these "pastéis de surpresa," surprise tarts, because everyone is surprised when you tell them what's inside. A vegetable? This sweetness, this richness, comes from a squash? It does. This is what Portuguese convent baking understands: transformation. Taking humble things and making them shine.

At Mesa da Avó, when I serve these, I always wait for the moment of revelation. The guests taste something delicate and golden, rich with egg yolk and cinnamon. Then I tell them. A squash. Grown in gardens. The grandmothers knew. They always know.
