Beetroot and Potato Salad with Smoked Mackerel

Excellent salad! It tasted very nice, and I also enjoyed the fact that I would never have dared to combine these ingredients. It also makes an excellent lunch box - or cat food; at least this is the very first dish our kittens have shown an immense interest in (though I'd rather give them only mackerel if I'd have to).

Edited 4 August 2013: When I served this as a lunch/picnic today, I forgot to add the horseradish cream, prompting my SIL to comment 'that the Jew in her longed for some gherkins', though she was quick to accept horseradish as a valid substitute once we found the jar with horseradish cream. I guess she was thinking of the Herring Salad with Beetroot and Gherkins her grandmother used to make (will have to make that some day...).

Served with Honey Chicken Salad and a rocket salad with Tarragon Vinaigrette. Served these dishes as a lunch to four people - I was afraid that it might be too much, but we finished it all!
