How to Thicken Sweetened Condensed Milk into Dulce de Leche: Step-by-Step Guide

This guide explores the process of transforming sweetened condensed milk into dulce de leche, a delicious caramel-like spread often used in various desserts and as a sweet treat. Whether you prefer a hands-on approach or a hands-off one, there are several methods you can use. This article will walk you through each method with detailed instructions and tips for achieving the perfect consistency and flavor.

Two Common Methods for Transforming Sweetened Condensed Milk into Dulce de Leche

Stovetop Method

For those who enjoy the hands-on experience of making dulce de leche, the stovetop method is a rewarding option. This method gives you full control over the consistency and color of the final product. Here’s how to do it:

What You’ll Need:

1 can (14 oz/ 400g) of sweetened condensed milk A saucepan with a heavy bottom or a double boiler

Instructions:

Prep the Milk: Pour the sweetened condensed milk into a saucepan or double boiler. If using a double boiler, fill the bottom part with water.

Cook Slowly: Set the heat to medium-low. Stir the milk frequently to prevent it from burning or sticking to the bottom of the pan.

Simmer: Allow the condensed milk to simmer for about 1-1.5 hours, stirring occasionally. The color will gradually darken, and the milk will thicken. Adjust the heat as needed to maintain a gentle simmer.

Finish: Once it has reached a deep golden color and a creamy consistency, remove it from the heat. Let it cool before using or storing.

Oven Method

If you prefer a more hands-off approach, the oven method is perfect for you. This method requires less attention and is a great option for those who don’t want to spend long hours in the kitchen.

What You’ll Need:

1 can (14 oz/ 400g) of sweetened condensed milk A baking dish like a glass or ceramic pie dish Aluminum foil A larger baking pan for the water bath

Instructions:

Prep the Milk: Pour the sweetened condensed milk into the baking dish.

Cover and Set Up Water Bath: Cover the dish tightly with aluminum foil. Place it in a larger baking pan and fill the larger pan with hot water until it reaches halfway up the sides of the dish with the condensed milk.

Bake: Bake at 425°F (220°C) for 1.5 to 2 hours, checking periodically to add more water to the bath if needed. The milk will gradually darken to a golden caramel color.

Stir and Finish: Once done, remove the dish from the oven, whisk the dulce de leche until smooth, and let it cool.

Slow Cooker Method

For those who want a very simple and hands-off approach, the slow cooker method is an excellent choice. This method is great for busy days, but it does take several hours to complete.

What You’ll Need:

1 or more cans of sweetened condensed milk (unopened) A slow cooker Water

Instructions:

Place Cans in Cooker: Remove any labels from the cans of sweetened condensed milk and place them in the slow cooker, making sure they’re fully submerged in water.

Cook on Low: Set the slow cooker to low and cook for 8-10 hours. For a lighter caramel, check after 8 hours. For a deeper, richer dulce de leche, let it cook closer to 10 hours.

Cool: Once done, let the cans cool completely before opening. This step is essential to avoid burns from pressurized hot milk.

Notes on Consistency and Storage

The longer you cook it, the thicker and darker the dulce de leche will become. The consistency can be adjusted based on your preference for a lighter or richer spread.

To store your homemade dulce de leche, place it in an airtight container. It can be stored in the refrigerator for up to 2-3 weeks.

Each method results in a thick, creamy, caramel-like dulce de leche that can be used in various desserts or simply enjoyed by the spoonful. Experiment with different methods and enjoy the deliciousness of homemade dulce de leche!
