Tip: There is no need to peel small new potatoes as they have very thin skins. Leaving the skin on helps retain flavour and also increases the fibre content. You can use left-over cooked potatoes, and add some baby spinach leaves for a complete meal .
Variations: Instead of using both mayonnaise and sour cream, just use one or the other. Replace the vinegar with lemon juice, and the spring onion with snipped fresh chives. Use prosciutto or salami instead of bacon.
