Tuna Shish Kebabs with Sweet Potato Fritters

Tuna shish kebabs with sweet potato fritters

Well, it's been a while! Life has taken a number of unexpected twists and turns for me over the past few years (some good/some bad) and I have had to focus my attentions on matters other than this long established project. I'm pleased to say that now I have managed to organise my life to an extent that I can revisit this blog on a regular basis and hopefully once again share with you tasty, healthy and moderately straightforward recipe ideas that you may wish to try for dinner tonight or any night. So let's take up where we left off a while back with this ultra tasty and healthy idea for tuna loin shish kebabs.

A shish kebab by definition is quite simply cubed bits of meat, threaded on to a skewer and cooked by grilling. While the meat from this originally Mediterranean dish would most often be lamb, goat, or perhaps even beef, there is nothing to stop us using moderately firm fleshed fish such as tuna.

Preparing sweet potato fritters batter

Method

Put 2 wooden skewers into a basin of cold water to soak for 10 minutes. This will prevent them burning during grilling.

When you are grating the sweet potato, do so into the centre of a clean tea towel or similar. Gather up the edges of the tea towel and squeeze hard over your sink to remove as much of the liquid from the sweet potato as possible. This is essential - do not ignore this step or your fritters will not come together properly.

Put the sweet potato into a large bowl. Add the beaten egg, coriander and flour. Season with salt and pepper and stir very well until a thick batter is formed.

Fill a deep frying pan with oil to a depth of about 2 inches (5cm) and bring it up to a medium to high heat. You could use a deep fryer if desired. The oil is hot enough when a little water splashed into it it spits noisily.

Put your kitchen grill (broiler) on to preheat to its highest setting.

Starting to fry sweet potato fritters

Use one or two dessert spoons to quenelle the sweet potato batter before carefully depositing in the hot oil. This much batter should make around 5 or 6 fritters. Adjust the heat under the pan if necessary to maintain a steady fry and turn the fritters carefully ever minute or so.

Tuna shish kebabs ready for grilling

As soon as the fritters are on to cook, thread the tuna chunks, courgette and bell pepper alternately on to the soaked wooden skewers. Lay them on some lightly oiled foil on a grilling tray and use a pastry brush to oil the tops of the kebabs. Grill for 3 minutes each side until done. Be very careful not to overcook the tuna!

Pour the soured cream into a small bowl. Add the grated garlic and most of the chives, reserving some of the chives to garnish. Stir well and transfer to a small ramekin for serving.

Draining sweet potato fritters

Lift the sweet potato fritters from the hot oil to a plate covered with kitchen paper to drain while you remove the kebabs to your serving plate.

A fork is best used to slide the tuna and vegetables from the skewers. Plate the potato fritters and dip, garnishing the dip with the last of the chives at the last minute.
