Rhubarb and Ginger Crumble with Oat Topping - Ireland traditional dish

🧂 Ingredients

  • 1 kg Rhubarb(trimmed and cut into 1-inch pieces)
  • 150 g Granulated sugar(adjust to taste)
  • 2 tbsp Fresh ginger(grated)
  • 200 g All-purpose flour
  • 100 g Rolled oats
  • 100 g Brown sugar
  • 125 g Cold unsalted butter(cut into cubes)
  • 0.5 tsp Ground cinnamon

👨‍🍳 Instructions

  1. 1

    Preheat oven to 375°F (190°C).

    💡 Tip: Preheating ensures the crumble cooks evenly.
  2. 2

    In a large bowl, combine the rhubarb pieces, granulated sugar, and grated fresh ginger. Toss gently to coat.

    💡 Tip: Using fresh ginger provides a more vibrant flavor than ground ginger.
  3. 3

    Pour the rhubarb mixture into a 9-inch pie dish or a similar-sized ovenproof dish.

    💡 Tip: Ensure the dish is oven-safe.
  4. 4

    In a separate medium bowl, combine the all-purpose flour, rolled oats, brown sugar, and ground cinnamon.

    💡 Tip: Mixing the dry ingredients first ensures even distribution.
  5. 5

    Add the cold, cubed butter to the dry ingredients. Using your fingertips or a pastry blender, rub the butter into the dry ingredients until the mixture resembles coarse breadcrumbs with some larger, pea-sized pieces.

    💡 Tip: Keeping the butter cold is crucial for a crumbly texture.
  6. 6

    Spoon the crumble topping evenly over the rhubarb mixture in the dish.

    💡 Tip: Don't press the topping down; a loose topping will be crispier.
  7. 7

    Place the dish on a baking sheet (to catch any potential drips) and bake for 40-45 minutes, or until the topping is golden brown and the rhubarb is tender and bubbling.

    ⏱️ 45 minutes
    💡 Tip: The baking sheet is a helpful precaution against oven messes.
  8. 8

    Let the crumble cool for at least 10-15 minutes before serving. This allows the filling to set slightly.

    ⏱️ 15 minutes
    💡 Tip: Serving warm is ideal, but not piping hot.

💡 Pro Tips

  • If your rhubarb is very tart, you may need to increase the granulated sugar slightly.
  • For an extra layer of flavor, add a tablespoon of orange zest to the rhubarb mixture.
  • Serve warm with vanilla ice cream, custard, or whipped cream.

🔄 Variations

  • Add a handful of fresh raspberries or chopped apples to the rhubarb filling.
  • For a nuttier crumble, add 50g of chopped walnuts or pecans to the topping mixture.
