Empanadas de Cajeta — Mexico's Flaky Goat's Milk Caramel Pastries
Cajeta is one of Mexico's most beloved confections — a thick, complex goat's milk caramel from Celaya, Guanajuato, where abundant fresh goat's milk and patient candymakers turned a simple reduction into something extraordinary. Unlike dulce de leche (its better-known cousin made from cow's milk), cajeta carries a faint tangy note from the goat's milk that keeps the sweetness honest. Wrapped in a shatteringly flaky lard pastry and baked until golden, it becomes an empanada de cajeta: one of the great handheld snacks of the Mexican panadería. These pastries are a staple of the Bajío region — Guanajuato, Querétaro, Michoacán — eaten as a mid-morning antojito or afternoon merienda, ideally alongside a cup of atole or café de olla. The term cajeta itself comes from the small wooden boxes (cajas) in which the caramel was originally sold to travellers passing through Celaya. You can still find Coronado brand cajeta in most Latin grocery stores today, and it works beautifully here — just make sure it's thick enough to hold its shape when spooned, or it will seep through the pastry during baking. The dough is a straightforward enriched wheat pastry: flour, lard, sugar, egg yolk, and cold milk. Lard is not negotiable if you want the characteristic crumbly, flaky texture and the slight savoriness that makes the sweet filling taste even sweeter by contrast. Butter works as a substitute — the result is more biscuit-like — but lard is what makes these empanadas taste like they came from a panadería in Guanajuato. The technique is simple: rub the cold lard into the flour until coarse crumbs form, bind with egg yolk and cold milk, chill, roll, fill, seal firmly, egg-wash, and bake. The most common failure point is underfilling (which wastes cajeta) or overfilling (which causes blowouts). A generous tablespoon per empanada is exactly right.
