Something about salted caramel defies reason. Shop-bought chocolate sauce starts to feel like a consolation prize after you’ve had a decent version of it, even though it’s sweet and salty, which shouldn’t work. It’s interesting to note how few people are aware that they can finish watching half an episode of a forgettable television show at home.
For good reason, the majority of home cooks end up using the condensed milk method. Refined sugar cannot match the inherent richness of a typical tin of sweetened condensed milk. When butter and soft brown sugar are mixed and allowed to gradually thicken over a low heat, the result is something that is truly hard to stop eating. If there is a trick, it’s patience. Almost invariably, it’s rushing the heat. Burnt caramel tastes just as bad as it sounds, and the mixture scorches quickly.
The majority of recipes require active cooking for ten to thirty minutes. The quicker versions, such as the straightforward drizzle made with dark brown sugar and vanilla, rely on the natural sweetness of the condensed milk and require very little technique. The longer techniques, such as simmering an entire unopened tin in water for three hours, result in something more akin to dulce de leche: it is denser, darker in color, and has a nearly toffee-like texture. Both strategies are legitimate. Although leaving a pot unattended on the hob is an act of quiet optimism that not everyone is comfortable with, the three-hour method is largely hands-off, meaning you can ignore it for extended periods of time.
The forgiveness inherent in the process is what makes the condensed milk version especially appealing compared to a traditional caramel, where you start by melting plain sugar until it barely avoids burning. There’s no panicking when you see amber tones through a pan. Here, the thickening is apparent, the color change is gradual, and the error margin is much larger. That is more important than it may seem to anyone who has ever ruined a batch of traditional caramel.
The salt itself merits serious consideration. The final flavor clearly shows the difference between using table salt and using proper flaked sea salt. Instead of creating a consistent background note, Maldon, which has become practically a shorthand for this type of cooking, dissolves unevenly into the sauce, producing sporadic bursts of salt. That is more intriguing to some people. When everything else in the recipe is so simple, it’s worth using the good ingredients even though it’s possible that others wouldn’t notice either way.
The sauce thickens significantly after it has cooled and been jarred. Before using, gently reheat it with a little milk to restore its pourable consistency. It’s obvious—almost too obvious—when poured over vanilla ice cream, but some combinations become classics for a reason. Perhaps the best thing any sauce can do is drizzle it over a crumpet on a gloomy weekday morning. It feels like a small but significant act of self-kindness.
