Baker’s Tips

No rhubarb? Substitute with chopped apples (add a little cinnamon) or tart berries like red currants or gooseberries for a similar sharp-sweet balance.

Dairy swaps:

  • Rahka (quark) is traditional in Finland, but full-fat Greek yogurt or sour cream works well.

  • For a richer tart, use crème fraîche.

  • For a lighter version, try a mix of yogurt and cottage cheese blended smooth.

Make it gluten-free: Use a 1:1 gluten-free flour blend with a pinch of xanthan gum. The texture will be slightly more crumbly, but still delicious.

Storage:

Keeps well in the fridge for up to 3 days. The base may soften slightly, but the flavour deepens. Gently reheat or serve cold with whipped

Ingredients

  • For the base:
  • 100g unsalted butter, softened
  • 85g caster sugar
  • 1 large egg
  • 1 tsp vanilla extract
  • 150g all-purpose flour
  • 1 tsp baking powder
  • Pinch of salt
  • For the filling:
  • 300g rhubarb, chopped into 1–2 cm pieces
  • 1 tbsp sugar (to sprinkle on rhubarb)
  • For the topping:
  • 200g sour cream or full-fat Greek yogurt (or Finnish rahka)
  • 1 large egg
  • 60g sugar
  • 1 tsp vanilla sugar or extract

Instructions

  1. Preheat oven to 180°C (350°F). Grease and line a 24 cm springform pan or tart tin.
  2. In a bowl, cream the butter and sugar until light and fluffy. Beat in the egg and vanilla.
  3. In a separate bowl, mix flour, baking powder, and salt. Stir the dry ingredients into the butter mixture until a soft dough forms.
  4. Press the dough evenly into the base (and slightly up the sides) of the pan.
  5. Scatter chopped rhubarb over the base. Sprinkle with 1 tbsp sugar.
  6. In another bowl, whisk together sour cream, egg, sugar, and vanilla. Pour evenly over the rhubarb.
  7. Bake for 35–40 minutes or until the top is set and lightly golden.
  8. Cool slightly before serving. Best enjoyed warm or at room temperature with coffee.
