Steps:

• Preheat the oven to 150C/130C fan/gas 2. Thinly slice the potatoes and turnips to about 2mm thick – you can use a Japanese mandolin if you have one – then toss together in a large bowl. Pour the cream in a pan, then add the garlic, plenty of salt and some white pepper – be generous when seasoning the cream as the potatoes and turnips aren’t seasoned separately. Bring the cream to the boil, then remove from the heat and put to one side. Grease a large gratin dish and layer a third of the potatoes and turnips in the dish, slightly overlapping each other as if you are building a wall. Pour over a third of the warm cream, then continue in this way with the remaining potatoes, turnips and cream.
• Put the gratin in the oven and cook for 20 mins. Remove the dish from the oven and push the potatoes and turnips down with a fish slice. This will help to release the starches and the cream will eventually reduce and thicken. Put the gratin back in the oven and repeat the process every 10 mins until the potatoes and turnips feel tight and firm. Return to the oven for another 20 mins and cook until golden brown and tender – test by inserting a sharp knife through the potatoes and turnips. Remove from the oven and leave to cool slightly.

Steps:

• Heat the oven to 190C/170C fan/gas 5. Cream the butter in a large bowl with a wooden spoon or in a stand mixer until it is soft. Add the sugar and keep beating until the mixture is light and fluffy. Sift in the flour and add the optional ingredients, if you’re using them. Bring the mixture together with your hands in a figure-of-eight motion until it forms a dough. You can freeze the dough at this point.
• Roll the dough into walnut-sized balls and place them slightly apart from each other on a baking sheet (you don’t need to butter or line it). Flatten the balls a little with the palm of your hand and bake them in the oven for around 10-12 mins until they are golden brown and slightly firm on top. Leave the cookies on a cooling rack for around 15 mins before serving.
