• Chicken: insert the chicken breast divided into 4 in two airtight glass jars. Add 3 lightly crushed juniper berries and 3 g of salt. Close the jar securely and cook in a dishwasher during an intensive washing cycle (75 °C for 2.5/3 hours). Remove the chicken pieces from the jars, discard the liquid and cut the chicken into cubes 1 cm per side. Chop up the chives and, in a bowl, mix them with the yoghurt and warm chicken. 
• Gruyère: : in the middle of a hot non-stick frying pan spread a little grated cheese from the centre outwards, like a spiral. Cook for 30 seconds on one side and 20 on the other. Remove it from the pan using a knife or a small spatula without a tip and place it on a cutting board, creating an irregular cone shape with slightly darker edges. Be careful not to scorch the cheese too much: it will become bitter. 

Plating: 
Pour the chicken seasoned with yoghurt and chives into a 12 cm cake ring. Place the crispy Gruyère cheese pieces on top, grate the truffle and finish with a sprinkle of chive.
