After working in Sonora, Mexico's remote Sierra Aconchi for four days on a biological survey, we decided to spend a night at La Posada del Río in Banámichi, a picturesque colonial town along the Río Sonora. Lovingly restored but decorated in bright modern colors, with a tropical plant-filled courtyard and antiques from around the world, it is truly a treasure. But the real treasure is the staff: friendly and helpful, everyone we met made us feel like we were guests in a home rather than a hotel. Chuyita Ruiz is the cook, and she prepared delicious Sonoran specialties such as tortilla soup, carne asada, machaca and eggs, and flan chiltepín. The latter, a classic Spanish custard but spiced with locally grown wild chiles, was out of this world, and we expressed our opinion vociferously. The next morning, Chuyita invited us to the kitchen for an impromptu lesson. Experiences like this are why we love to travel.
To make the caramel, add 1 cup sugar to heavy pan and stir constantly over medium-high heat.
The sugar starts to melt and caramelize. Keep stirring so it does not burn.
Continue stirring until rich, dark caramel-brown.
Carefully pour the hot caramel into the tin mould, swirling to coat the whole inside. Careful, the molten sugar sticks and burns skin very badly (notice how Chuyita is holding the tin as she swirls it, keeping her hands well away from any drips). The mould is a Christmas cookie tin with a lid.
Prepared mould, set to cool while the batter is made.
Mix the batter in a blender: 1 can evaporated milk, 1 small can sweetened condensed milk, 8 oz. cream, 4 eggs, 1 t. vanilla. Add flavoring or not. Chuyita made one with chiltepines (very hot wild chiles, a specialty of the Río Sonora region) about 10 crushed finely; or a tablespoon of instant coffee. (If you prefer not to used canned milks, you can use whole milk and eggs: Add 2 cups milk and salt to a medium saucepan over medium heat. Bring milk to a brief simmer. Do not let the milk come to a boil. Remove from heat. In a mixing bowl combine 6 eggs, 1/3 cup sugar and 1 tsp. vanilla and beat well, until light and foamy. Add milk to the egg mixture, whisk continually.)
Pour the batter on top of the caramel.
Place the lidded tin in a simmering water bath.
Cook in the water bath for 45 minutes.
Fresh from the water bath. Let cool a bit before inverting.
Place a pie plate over the tin and invert.
