Step 1

For pecan crumble, place flour, oats, caster sugar, cinnamon and a pinch of salt in a bowl and mix to combine, then rub in butter with your fingertips until clumps form. Mix in pecans, spread on a tray lined with baking paper and freeze until firm (10-15 minutes).

Step 2

Preheat oven to 160C and line a baking tray with foil. Whisk maple syrup, mandarin juice and lemon juice in a bowl. Combine pears, dates, brown sugar, cinnamon, 1 tsp mandarin rind and a pinch of salt in a separate bowl, and toss to coat, then transfer to a 25cm-diameter cast-iron frying pan or baking dish, or three 16cm-diameter cast-iron frying pans. Pour maple syrup mixture over pears, sprinkle with crumble, place on prepared baking tray and bake until crumble is golden and filling is bubbling (45-50 minutes for small crumbles, 1-1¼ hours for larger crumble). Stand to cool briefly (10 minutes).

Step 3

Meanwhile, whisk remaining rind in a bowl with yoghurt and serve with warm crumble.
