Potato and apple salad with mackerel recipe

Potato and apple salad with mackerel is a great way to refresh a traditional potato salad recipe. The combination of potatoes, apple, fennel and beetroot make this a deliciously fresh salad, perfect for a hot summers day. Smoked mackerel is a great salty contrast to the creaminess of potato salad and will work perfectly as a whole fillet for a meal or flaked into the salad as a sharing bowl for BBQs and summer parties.

• 100g (31/2oz) fennel (½ bulb), trimmed (keep the fronds) and finely diced
