Marmalade rusks

1. Preheat the oven to 170°C and grease a 32 x 42 cm baking tray.
2. Mix the flour, baking powder and salt. Rub in the butter with your fingertips until it feels like coarse breadcrumbs.
3. Mix in the muesli, sultanas or raisins, seeds and coconut.
4. Place the sugar in a separate bowl and rub in the orange zest. Stir in the buttermilk, marmalade and eggs.
5. Pour the buttermilk mixture into the centre of the flour mixture, and stir well using a wooden spoon.
6. Spoon the mixture into the greased baking tray.
7. Bake for 45–50 minutes, until a skewer comes out clean and the sides of the rusks pull slightly away from the tray. They should be golden brown.
8. Leave to cool slightly, turn out onto a wire rack, then allow to cool completely.
9. Cut into rusks 1–2 cm wide and 6–8 cm long, and spread across two baking trays, with space in between for air to move.
10. Dry in a 100–120 °C oven for 5–7 hours until the rusks are hard. Near the end, watch out that they don’t overbake and get too dark.
11. Once they have cooled completely, store the rusks in airtight containers lined with paper towel.
