Rhubarb Crumble with Crème Fraîche

Inspired by Södermalm bistro favorite Cafe Nizza, this dessert balances rustic simplicity with dialed-in restaurant contrast. Tender batons of ruby rhubarb—scented with freshly ground green cardamom and vanilla bean—are baked until juicy yet structurally intact, crowned with a crisp browned-butter hazelnut crumble. The magic lies in the temperature and acid clash: molten, tart-sweet fruit against a cold, luscious quenelle of cultured crème fraîche.

Ingredients

The Cardamom Rhubarb

• 1.1 lb fresh rhubarb, trimmed and sliced into 1.5-inch batons
• 0.33 cup granulated sugar
• 1 tsp freshly ground green cardamom seeds
• 1 tsp vanilla bean paste
• 1 tbsp fresh lemon juice

The Brown Butter Crumble

• 5.5 tbsp unsalted butter, browned and cooled
• 0.5 cup all-purpose flour
• 0.5 cup rolled oats
• 0.33 cup raw hazelnuts, finely crushed
• 0.25 cup light brown sugar, packed
• 0.5 tsp flaky sea salt

To Serve

• 0.75 cup chilled crème fraîche (34%+ fat)

Instructions

1. 1
   Brown the Butter

   Melt butter over medium heat until foamy, fragrant, and dotted with amber milk solids. Cool 10 minutes.

2. 2
   Toss the Rhubarb

   Toss rhubarb batons with sugar, cardamom, vanilla, and lemon directly in your shallow stainless or copper baking pan.

3. 3
   Assemble Streusel

   Whisk flour, oats, hazelnuts, brown sugar, and salt. Pour in brown butter, pressing into rough, uneven pebbles.

4. 4
   Bake to a Bubble

   Scatter streusel over fruit. Bake at 190°C (375°F) for 25 minutes until juices simmer thickly and topping crisps.

5. 5
   Finish Cold

   Rest 5 minutes. Crown immediately with cold crème fraîche so it gently melts into the piping-hot fruit.

Bistro Technique: Keep the Batons Intact

Avoid dicing the rhubarb into small cubes. Cutting into uniform 1.5-inch batons keeps their structural integrity under heat, preventing a mushy compote and giving you that distinct restaurant mouthfeel.

Pairing Note: Serve with a chilled glass of Coteaux du Layon or sparkling Bugey-Cerdon to balance rich browned butter with razor-sharp acidity.
