What is a 'fermented food'?

Fermentation is a hot health topic right now. But what exactly is a fermented food? It might sound like a fad, but fermentation is an ancient technique – initially developed to preserve food – which dates back thousands of years. In essence, a food becomes fermented when microorganisms, such as bacteria and yeast, are added and break down food compounds.

Sound strange? You’ve probably got plenty of fermented foods in your kitchen right now. Yogurt, for example, is made by mixing friendly bacteria into milk, while sourdough bread dough is created using a starter of fermented flour, water and salt.

How to get your fermented food fix

From sourdough to sauerkraut, it’s easy to get your fermented food fix – try some of our favourites from the Foodhall in this delicious open sandwich.

1. Our Collection seeded sourdough is made with only flour, water and our sourdough starter, which is then slow fermented. Try it toasted.

2. Spread with our Collection labneh yogurt dip – a creamy strained yogurt with a basil and mint dressing and za’atar style sprinkle.

3. Top with sliced pickled beetroots and diced cucumber to add freshness, crunch and more plant diversity.

4. Finish with a spoonful of our naturally fermented Vadasz raw garlic and dill sauerkraut, which is live cultured and brings a delicious tangy flavour.

The flavours of fermented food

As well as some of their potential health benefits, fermented foods come in a wonderful array of flavours and can ensure all sorts of dishes pack an extra punch.

Think about that umami-rich, sour tang you get from yogurt or cheese – it's all down to the fermentation process. Miso will add depth and savouriness to soups and stews, while kimchi is amazing in a cheese toastie. If you'd like to incorporate more fermented foods into your diet, it's a good idea to start with a small amount each day, before increasing gradually.
