These are the two side dishes from my main course of Slow Roasted Beef for the 20 Mile Cookalong. The potatoes came from Keoghs in Oldtown and the courgettes from Marc Michel. I was able to purchase both of my vegetables from Morton's in Ranelagh, which you should definitely drop in to if you're looking for interesting Irish products.

First up is the horseradish mash, very simple, but the perfect accompaniment to the beef. The second side is fried courgette strips, again very simple, but, in my opinion, the nicest way to serve courgettes.

For the horseradish mash, first peel the potatoes, cut in half and put in a pot with water just covering them.

Bring the potatoes to the boil and cook until a knife will slide into a potato easily.

While the potatoes are boiling, peel the horseradish and finely grate it. Keep a tissue near by as I guarantee your eyes will end up watering when you're grating the horseradish.

When the potatoes are done, add the horseradish, butter and a splash of milk to the pot.

Mash the potatoes together with the other ingredients. Season with salt and pepper to your tastes.

Moving on to the courgette side dish; trim the ends off the courgettes and thinly slice with a sharp knife, a mandoline or with the slicer part of a grater.

Heat some oil in a frying pan and when hot, fry the courgette strips in batches until golden on both sides. Alternatively you can brush the courgette with a little oil and put under a grill, again until golden.

Serve both dishes on the side with beef, or anything else you fancy.
