Written by Maria Guadalupe Reyes

Sopa De Natillas
"Se vaten las Natillas con una poca de Leche Azucar competente Yemas de huevo y en una Cazuela embarrada de Manteca se va poniendo mamon en Leche hasta qe. se llene luego se echa el batido por encima mucha Natilla ya que se a dos fuegos y ente se le echa Canela por encima."
English Translation
"The custards are beaten with a little milk, enough sugar, egg yolks, and in a pan greased with butter, you put sponge cake in milk until it is filled, then you pour the beaten mixture on top, a lot of custard, then it goes on two fires and between them, you sprinkle cinnamon on top."
Note on the Original Text
The recipe, like many of its time, is terse and intended for cooks already familiar with domestic techniques. Quantities are relative ('poca de leche', 'competente yemas de huevo'), and steps assume a grasp of how to layer and bake custard-soaked breads. Spelling reflects early-19th-century Mexican orthography—'vaten' for 'baten' (whisk), 'cazuela embarrada de manteca' (casserole smeared with butter/lard), 'mamon' (soft cake or bread). The absence of times and temperatures requires an experienced cook to judge doneness by look and feel, a skill expected in historic kitchens.

Sopa de Natillas appears in the 1828 manuscript 'Libor de Gisados y repostería de Maria Guadalupe Reyes', a remarkable culinary notebook documenting Mexican recipes from the early 19th century. At this time, Mexican kitchens were a blend of Spanish, Indigenous, and other European culinary influences. Recipes were often passed down orally or recorded in household notebooks like this one, reflecting both everyday and celebratory fare. This particular dish exemplifies the adaptation of European-style custards (notably natillas, a Spanish dessert) into local tradition, using readily available dairy, eggs, and breads, layered and finished with the ever-popular cinnamon.

The original recipe would have been made using a large earthenware or clay cazuela (casserole dish), a wooden whisk for beating egg yolks and sugar, and simple kitchen knives. The baking or setting would be done over an open fire or in a wood-fired oven, often with heat coming both from below and from above, by using embers placed on top of a heavy lid. Cinnamon would be ground with a mortar and pestle. All utensils and mixing bowls would be rustic, likely hand-crafted, and the butter used to grease the cazuela would be freshly churned.
