Dauphinoise Swirl

Instructions

1. Transfer the cashews to a bowl and cover them with hot water straight from the kettle. Leave to sit for at least 20 minutes.
2. If needed, cut the large potatoes in half so that they’re roughly 5cm wide and add them to a saucepan of cold water on a high heat. Cover with a lid and bring the water to the boil, then boil gently for 25 minutes until the potatoes are parboiled. It’s important they’re not too soft so you can slice them later.
3. Drain the cashews and add them to a blender. Peel the garlic and add it to the blender along with the nutritional yeast, generous pinches of salt and pepper, and 500ml (17fl.oz / 2 cups) of water. Blend until smooth and set to one side for later.
4. Preheat the oven to 200ºC / 390ºF fan-assisted.
5. Drain the potatoes and slice them as thinly as possible (around 1-2mm thick).
6. Arrange 1/3rd of the potato slices in a swirl in the base of a round ovenproof dish. Then pour 1/3 of the sauce on top and sprinkle with the leaves from 1 sprig of rosemary. Repeat this step for another 2 layers placing the potatoes in a swirl and topping with sauce and rosemary leaves each time. Bake the swirl in the oven for 20 minutes.
7. Remove the dauphinoise swirl from the oven. Check the potato has cooked fully (return it to the oven for another 5-10 minutes if not) and top with salt and freshly ground black pepper. Et voila!
