Curtido is a Salvadoran fermented cabbage dish, rather like sauerkraut but with a twist.

The base is still cabbage and salt, but curtido adds onion, carrot, jalapeno and dried oregano.

Packed with nutrients, it has been a staple of food in El Salvador for years.

If you see curtido or sauerkraut in a supermarket, make sure that you read the label before you buy it.

Most store-bought krauts are not actually fermented. Instead, they just add vinegar to cabbage to create that distinctive fermented flavor.

Without fermentation, these krauts will be much less beneficial for your immune system and digestion.

As with so many foods, making your own curtido or sauerkraut at home is the best way to go!
