Preheat the oven to 220°C (200°C fan, gas 7). Grease a muffin tin with butter.
Dust the tin with flour and tip out the excess.
Combine the flour with the crumbs, salt, baking powder and cheese. Purée the oil with the pine nuts, mix with the buttermilk and eggs in a bowl. Season with paprika and cayenne pepper. Mix the flour mixture with the wet ingredients briefly, so that all the ingredients are moist.
Spoon the mixture into the tins and bake for 35 minutes. Remove, allow to cool briefly, remove from the tin and allow to cool.
