Dulce de Leche

My son is currently showing an interest in learning about different countries around the world and so we decided to choose one country and do a project on it. His choice was Argentina and while he showed more interest in the national sport and animals, I found myself more interested in the traditional foods (surprise, surprise).

What I never knew was that one of my favourite sweet sauces, Dulce de Leche originates from Latin America. I’ve also never made my own Dulce de Leche, opting rather for the easy, off the shelf version or I make caramel sauce with cream, butter and sugar.

As convenient as the tinned version is I have always thought that there is a slightly unpleasant after taste so I was keen to try and make my own. I was surprised to see that the original version of Dulce de Leche uses only milk, sugar and bicarbonate of soda and so I thought I would give it a try…

… and what started out as a simple ‘I wouldn’t mind trying that out’ became a bit of an obsession. Three days later and I have 5 jars of gorgeous, creamy, sweet, finger lickin’ good Dulce de Leche to use in all sorts of goodies in the run up to Christmas.

My first attempt was to empty a tin of condensed milk into a glass dish and bake in a water bath for about 2 hours. As the sugar in the condensed milk caramelises it turns into a beautiful golden brown and thickens up beautifully. This was the most fuss free of all methods but I did find the end result was very, very sweet and I wasn’t convinced that using a tin of condensed milk was particularly authentic. It also gave a similar aftertaste to that of the ready made tinned version.

My second attempt was to try microwaving the condensed milk in a glass bowl. This was my least favourite method. It was quick and gave the best colour but I found it hard to judge when the sauce was ready and ended up with something which resembled fudge more than a sauce.

My third attempt was to try the original method which is to boil milk, sugar and bicarb until the water evaporates from the milk and the sugar caramelises. This method was a bit more labour intensive but the flavour is far superior to the condensed milk version. The sweetness is much more subtle and just gives a nicer, smoother sauce.

I did not try the method of boiling a tin of condensed milk as I thought the end result would be too similar to the baked version.

So next time you have a spare morning at home give this a try and I guarantee you will never buy the tinned version again …

Dulce de Leche

A deliciously sweet and creamy dessert sauce - perfect for filling cakes and cookies, over ice cream or straight out the jar. Finger lickin' good!

Prep Time 5 mins
Cook Time 2 hrs
Total Time 2 hrs 5 mins
Servings 500 ml


  • 2 litres semi skimmed milk

  • 500 g sugar

  • ¼ 

    tsp bicarbonate of soda


  • Place all ingredients in a large, heavy pan. On a medium heat stir until the sugar has melted.

  • Reduce the heat to as low as possible and leave to simmer for another 2 - 2½ hours.

  • Note - During the first hour I did not have to do anything - no checking and no stirring. The next ½ an hour I just kept a close eye on the sauce and stirred every now and again. For the last ½ an hour I stirred almost constantly to prevent the sauce from sticking to the pan. For the consistency that you see in the photos I stopped when the sauce was still quite runny in the pan (100° C on a sugar thermometer). It firms up once it has cooled down.



Will keep in the fridge for over a month. It may need to be warmed up slightly to soften before use.
