Rhubarb Apple Crumble

This crumble is rustic, crunchy, deeply comforting, and not too sweet. Make it while rhubarb season lasts – it really lets the rhubarb flavour shine through.

Rhubarb Apple Crumble

This is a very versatile recipe. You can change the fruit filling or twist the flour/nut mix to your taste. Feel free to increase or lower the sugar to your liking, too – this makes for a slightly tart crumble. 
serves 6-10
For the topping:
65g/ 1/2 cup whole wheat flour
35 g/ 1/4 cup oat flour
45 g/ 1/2 cup rolled oats
1/4 cup pistachios, toasted and roughly chopped
1/4 tsp sea salt
60 g/ 1/3 cup natural light brown cane sugar
65 g/ 1/4 cup cold unsalted butter, cubed into 1/4-inch pieces
 For the filling:
1 tbsp oat flour
75 g/ 1/2 cup light brown sugar
about 2 small granny smith apples, cored and cubed into 3/4-inch pieces
about 4 stems of rhubarb (350g , about 12 oz), cut into 3/4-inch pieces

zest and juice of one unwaxed organic lemon

Preheat the oven to 375F / 190C. In a medium bowl, combine the flours, pistachios, oats, sugar, salt. Stir in the butter and use your fingers to incorporate it into the flour mixture. The final result should be crumbly and lightly sticky. Set aside (you can also refrigerate it for 10 minutes).

In the meantime, make the filling. In a large bowl, whisk together the oat flour and sugar. Add the apple and rhubarb, and toss until evenly coated. Pour lemon juice, add lemon zest and toss once again. Transfer the filling into a pie dish or baking pan, then sprinkle the topping mixture all over the fruit.

Bake for about 40 minutes, or until the topping is crispy and golden and the filling is bubbly. Cool for about 15-20 minutes before serving. Serve on its own or with whipped cream.

      Ma grazie! Il rabarbaro ha quel saporino un po' acidulo che conquista proprio, l'ho scoperto anch'io di recente ed è stato amore al primo morso!

    Quelle stringhe di rabarbaro curve, come fossero caramelle.
    Ma prima o poi ce lo facciamo insieme, e lo mangiamo dalla ciotola a cucchiaiate, con the e chiacchiere. Oh sì sì.
