Wash and peel the yellow potatoes well, then chop them into medium pieces. Take the pieces to a metal pot or pan with enough water to cook them over medium heat. Water is added to cover them completely so that the potatoes are very soft so that they can be crushed easily.
While the potatoes are cooking, in a small pot you can add the butter to melt it over low heat. While it melts add the ground garlic and a little salt, when the garlic has browned add the evaporated milk, the BBQ sauce for a smokey flavor, and mix.
When the potatoes are ready, they are crushed until a puree is obtained and then added to the mixture of the other ingredients. Stir well until the ideal texture of a purée is obtained. If necessary, you can add a little more milk or, failing that, a little water. Leave for approximately 5 minutes over low heat and remove to serve.
As an optional step, you can cook some bacon in a saucepan, chop it into small pieces and use it as a topping.
