CONFITURE DE LAIT IN LYON, FRANCE
In Lyon, we had canelé served with confiture de lait, a sauce of caramelized milk. The translation would be something like milk jam. It is a method of preserving milk by cooking it with sugar. This is more commonly known in the United States by the Spanish name of dulce de leche, since it is popular in Mexico.
A quick and easy way to make confiture de lait (dulce de leche) is to use sweetened condensed milk, since it is already thickened and sweetened.
The only other ingredient needed is baking soda. A very small amount of baking soda will help brown the sauce to a deeper golden brown color. Milk is naturally a little bit acidic (pH below neutral). Adding the baking soda, which is basic (pH above neutral) will change the milk from slightly acidic to a more balanced pH. The amount of baking soda is so small that you won’t taste it in the confiture de lait (dulce de leche).
MAKING CONFITURE DE LAIT (DULCE DE LECHE) RECIPE IN AN INSTANT POT
Using an Instant Pot makes this really fast and easy. Just pour the condensed milk into a smaller insert pan and set it over water in the Instant Pot main pan. This makes the Instant pot like a double boiler, keeping the milk from scorching. There is no stirring or checking on it required. It takes about an hour.
Alternative methods take much longer, and are more trouble. Methods like cooking it in a double boiler for three hours – or in a can in the oven for four hours – or in a slow cooker for twelve hours. This is also safer than leaving it in a can and creating pressure by heating up the can. And it doesn’t create a mess with the glue from the label on the can.
And this is by far the most energy efficient way to do this, since the Instant Pot uses less energy than a slow cooker and far less than an oven.
The confiture de lait is stored in a jar, and will keep refrigerated for weeks.
