Brush a 23cm springform tin with some melted butter. Set aside 30g of the grated cheddar, and mix the rest with the other cheese, apple and chutney or pickle. Knock back the dough by gently kneading just 5 times to get the air out. Cut the dough into 12 even pieces (use a weighing scales if you like). Roll each piece into a ball, the roll out to form a disc and divide the cheesy filling between them. Shape back into smooth balls by pinching the edges together. Arrange, seam-side down, in the tin.
