Cauliflower tempura
A healthy, Japanese-style snack
In a small bowl pour 1 tbsp of boiling water over the saffron and set aside. Put the garlic, egg yolks and mustard into a food processor or blender. Blitz into a paste and very slowly dribble in the olive oil to make a thick mayonnaise-style sauce. When everything's come together add the saffron, saffron water and lemon juice, then season to taste. The aïoli will keep covered in the fridge for up to 2 days.
