Place the feta, cream, lemon zest, garlic, mint and black pepper into a food processor. Blend on high until smooth, about 2-3 minutes. Season to taste and spoon into a serving bowl.
In a saucepan heat the butter until it just begins to turn golden brown. Add the fennel seeds and sizzle for a minute. Add the nduja, honey and salt. Mix well and warm everything through, take off the heat and add the lemon juice.
Drizzle the butter mixture over the whipped feta and serve with toasted pittas, flat breads, crudités or my seeded crackers (see below)
