Potato and dill rosti with roast garlic aioli, pickled cucumber and confit tomatoes by Manuel
The great thing about rostis, like potatoes, is that they are versatile. You can have them as part of a breakfast, with eggs, fish, with salad elements or just by themselves with a condiment. Feel free to vary the size, but bare in mind the cooking times. Mine were quite thin and the width of a crumpet. I would make them thicker next time.
Inspired by the recipes of Richard Buckley, I decided to pair my rostis with pickled cucumber, confit tomatoes and roast garlic aioli, which brings a balance of sweetness, freshness and richness to the dish. A little note on these recipes also, I recommend reading them through before cooking as they take time. Some things ideally take overnight to make, or a few hours to rest or chill.
Rosti
400g Mira potato
50g onion
1 tsp salt
15g flour
A handful of dill
- To begin, prepare an ice bath, cold water and ice in a bowl. We will plunge the partly cooked potato into this bowl.
- Add the potatoes to a large pot, cover with water. Season the water. I go for a big pinch then taste the water, as a wise man said, you want it to taste like the ocean. I add a splash of vinegar also, about half a teaspoon. This helps the potato crisp up later...apparently.
- Simmer the potatoes for about 5-7 minutes. Check them regularly, you don’t want them to be cooked all the way through, just enough for the tip of a knife to pierce without too much force.
- Drain the par boiled potatoes and place into the ice bath.
- Now, when chilled, dry off the potatoes, let them chill further in the fridge for a few hours. When assembling the rosti you want to be using cold potato.
- In the mean time, slice some onion. Heat a pan with 2 tbsp of rapeseed oil and gently fry on a low heat. Do this for 10-15 mins, you want them cooked down until they look glassy. Once cooked set aside.
- When you are ready for the rosti, ideally you want to use a mandolin with a julienne setting. Alternatively you can use a box grater. Grate the potatoes and add to a bowl.
- Chop and add the dill, flour, salt and onion to the bowl with the grated potato and mix until the potatoes start to feel a little sticky from the flour.
- Now form a pattie. I made mine about 1cm thick and used a crumpet ring mould. If you don’t have a ring then you can just use your hands, a thick jar lid or a shallow circular tub to help you shape.
- Pre heat your oven to 160C
- Now to fry. A non stick pan would be ideal here, but if you don’t have one use a good glug of sunflower or rapeseed oil. Get the pan nice and hot then add the oil. Place in 1-2 rosti in the pan (depending on the size). Rostis can be delicate, use a spatula to help you move them.
- Turn the heat down to medium-low and cook for about 5-6mins
- Now to flip it, I use a spatula and then another implement to help them over. A small plate or another spatula will work.
- Cook for a further 5-6 mins. The topside of your rosti should look golden brown.
- Now, place the patties into the oven for 10 mins to ensure the center is cooked through.
Pickled cucumber
1 cucumber (160g)
1/2 tsp salt
4 tbsp cider vinegar
1 tbsp caster sugar
1 tsp salt
3 tbsp water
- Using a mandolin, ribbon the cucumber. Alternatively you could slice it into round, cutting on an angle.
- Mix in the half tsp of salt with the cucumber and leave for one hour. The salt will draw water from the cucumber
- In the mean time combine the brine ingredients in a bowl with a whisk. This is a cold pickle so no need to heat the brine.
- When ready, drain the cucumber and rinse under cold water. Pat dry.
- Add the cucumber to the pickling liquid. Pickles are made.
Confit tomato
235g tomato (I used large cherry tomatoes, about the size of ping pong ball)
1/2 tsp salt
1/2 tbsp red wine vinegar
2g rosemary
2 cloves garlic
100ml olive oil
- We will start by blanching the tomatoes. To do this, prepare and ice bath, and bring a pot of water to the boil.
- Cut a small X in the bottoms of the tomatoes.
- Add the tomatoes to the pot, as soon as you see the skin peeling away, lift them out. Mine took about 30 seconds. Drop them into the ice bath
- When cold, peel the tomatoes carefully, add them to a bowl with the salt and leave them for an hour, they should expel some tasty juices.
- Then, add the vinegar, rosemary and garlic to the tomatoes. Leave for at least an hour but preferably over night.
- When ready to continue, preheat the oven to 140C
- Remove the tomatoes from the marinade and half them. You can keep the marinade for later.
- Now, we want to submerge the tomatoes in olive oil.
- Using a small tin, pack it with the tomatoes laid face down.
- Add the olive oil, it took me about a 100ml to just about cover them
Note : if you don’t have a small tin and don’t want to use copious amounts of oil, just give them a drizzle to achieve slow roasted tomatoes.
- bake the tomatoes in the oil for about 30 mins, keep an eye on them, you don’t want them to break down.
- Remove the tomatoes from the oven and allow them to chill to room temperature. Remove them from the tray with a spoon into a tub as they are delicate.
- The oil can now be added to the marinade left overs, you now have a tasty tomato oil you can use to garnish a plate or for salads.
Roast garlic aioli
For the roast garlic :
1 head of garlic
Olive oil
- Preheat the oven at 160 C
- Cut the bottom from the head of garlic enough to reveal the cloves
- Mix the garlic with a little olive oil and wrap in foil
- Cook for 30-40 mins in the oven
- To check its ready carefully unwrap the foil and poke the cloves, they should be soft and smelling amazing
- When cooked, allow to cool and remove the cloves, I use the handle end of a teaspoon to scoop them out.
Aioli:
1 head of roast garlic
4 tbsp of Aquafaba (chickpea water)
3 tsp cidar vinegar
3 tbsp olive oil
100ml sunflower oil
1/2 tsp salt
Pinch of cayenne
Pinch of paprika
- Measure out all ingredients into a heavy based jug
- Using a hand blender, on the slowest setting blend the contents.
- We now need to incorporate the oil slowly whilst blending
- Pouring from another jug, add the sunflower oil, slowly in a steady stream whilst blending.
- Moving the blender up whilst you add the oil keep going until the mix thickens and you can start to see peaks form when you lift out the blender from the mix
Plating
Now all your components are made you can plate. Swipe some aioli on the plate and get creative, garnishing with more dill, salad leaves and the marinade oil. Alternatively chuck it all between some fresh sourdough and enjoy a very decadent sandwich!
