Preheat the oven to 175 degrees Celsius (350 Fahrenheit)
Place the cauliflower florets on a baking sheet and drizzle with olive oil. Bake in the oven for approximately 20 minutes until the cauliflower is tender and golden in colour
Transfer the roasted cauliflower to a food processor along with all of the remaining ingredients and blend until completely smooth. You may need to add a splash more water to get the dip smooth. Taste and adjust the seasoning by adding more spice or lemon juice as needed.
