    hors rad-ish

    Horseradish root is larger than an ordinary radish, and has a hot, peppery flavour.



  1. Put the potatoes in a microwaveable bowl with a splash of water, cover, then cook on high for 5 mins until tender (or steam or simmer them).

  2. Meanwhile, heat the oil in a frying pan over a medium heat, add the leeks with a pinch of salt and cook for 10 mins, stirring so they don’t stick, until softened. Tip in the potatoes, turn up the heat and fry for a couple of mins to crisp them up a bit. Flake through the mackerel.

  3. Make four indents in the leek mixture in the pan, crack an egg into each, season, then cover the pan and cook for 6-8 mins until the whites have set and the yolks are runny. Serve the horseradish on the side, with the pan in the middle of the table.

We really enjoyed this. Good ingredients and very filling. I did roast the new potatoes before adding to the pan to give them a good texture and flavour. I also poached the eggs and served on top of the hash as I have tried to cook them in hash recipes before and they end up either undercooked or overcooked! Didn't bother with the horseradish as we don't like it.

I did not think that I would like this as I’m not that keen on mackerel. However it was really tasty and filling. I did use plain smoked mackerel (by mistake) and used more potatoes as I’ve got a hungry husband! Also added the horseradish to the pan with the leeks and potatoes. A keeper.

Quick, delicious and filling. I forgot the horseradish so will include it in the mix next time. I added a thinly sliced green pepper and some peas too.

I followed the recipe and tweaked it as per Pam T. First time i made it tonight. Really tasty, super quick and so filling. Highly recommend!

This was delicious. The only changes I made were to crush the cooked potatoes slightly, which made it easier to make the indentations for the eggs, and add the horseradish to the pan as suggested by CeriB. A tasty, thrifty meal.

I made this for tea and it was delicious, I made a few changes to it though. I sauteed the leeks with an onion and garlic, then when soft added a dessert spoon of Dijon mustard and took off the heat and put into a bowl. I then sauteed the potatoes for a couple of minutes added the mackerel and continued for 2 minutes. I then added the eggs and put it under the grill for a few minutes, then served on the plate with a squeeze of lemon juice.

I made this last night - a delicious, quick and cheap meal for two. Instead of leaving it to the end, I added two dollops of horseradish to the potato and leek mixture once it entered the frying pan, then the mackerel and eggs. Worked a treat!

Very easy to make and very tasty. The only change we made was to mix the horseradish in with the main dish rather than having it on the side.

Made this last night and enjoyed it; it's a bit different so makes a nice change. I always struggle to get the eggs cooked when they're baked in this way and this recipe was no exception. As I can't stand runny white, I popped the pan under the grill briefly to set the top of the eggs.
