Do not boil a sealed tin. The traditional way to make dulce de leche is to simmer an unopened tin of condensed milk for three hours. It works, and it is three hours of gas, and a tin left to boil dry can burst. Opening it and cooking it in a pan takes eight minutes.
- Almonds toasted dry, tipped out.
- Condensed milk into the pan over a low heat with the salt. It catches and scorches easily, so keep it low and keep stirring.
- Eight to ten minutes, stirring almost constantly, until it turns from cream to a proper fudge-brown and thickens. It will look unchanged for five minutes and then move quickly. Stay with it.
- Drained fruit cocktail into bowls, the warm caramel poured over, almonds on top.
The salt is what stops it being flatly sweet, and a pinch more than feels right is usually correct.
