Sous vide fennel and orange quinoa salad

Preheat a water bath to 85°C

Add the quinoa and vegetable stock to a medium saucepan and bring to a simmer. Continue to cook for 15 minutes, or until the quinoa is cooked through but retains a bit of bite. Remove from the heat and leave to cool

Meanwhile, prepare the fennel. Place the fennel pieces in a vacuum bag and add the orange juice and saffron. Seal the bag and place in the preheated water bath for 20 minutes

Place a frying pan over a high heat, then remove the cooked fennel from the bag and add to the hot pan. Sear the fennel until coloured on all sides, then remove from the heat and mix together with the cooked quinoa. Stir through the pomegranate seeds, toasted sesame seeds and chopped coriander and mix together until combined

In a small bowl, mix together the olive oil and lemon vinegar to make a lemon dressing. Stir a little into the quinoa and season with salt and pepper. Check the quinoa salad for taste, seasoning and adding more dressing to taste if required

Place the frying pan over a low heat and add the pine nuts, toasting gently until evenly coloured. Sprinkle over a pinch of salt and toss rigorously in the pan to combine. Tip the toasted pine nuts onto a small plate to cool slightly before adding to the salad

To serve, divide the fennel and quinoa salad between serving plates, topping each portion with a sprinkling of the toasted pine nuts. Arrange the orange segments on top of the salad and garnish with the nasturtium leaves and coriander cress. Whisk together the tahini, lemon juice and olive oil in a small bowl and drizzle over to finish
