AT A GLANCE
Best-quality butter puff - whether homemade or store-bought - is really the making of this tart.
|01||For candied seeds, stir ingredients in a saucepan and over medium-high heat until sugar begins to crystallise and cling to seeds (8-10 minutes). Spread onto a baking tray lined with baking paper and set aside to cool. Seeds can be stored in an airtight container for up to 1 month.|
|02||For frangipane, beat butter and sugar in an electric mixer until pale (3-5 minutes), add vanilla and almond meal, then beat on low speed until well combined (1-2 minutes). Refrigerate until required. Frangipane will keep for 3-4 days; use straight from fridge.|
|03||Preheat oven to 180C. Roll out pastry on a lightly floured surface to a 12cm x 35cm rectangle, then transfer to a baking tray lined with baking paper and dock all over with a fork. Spread a thin layer of frangipane over pastry, leaving a 2cm border. Arrange rhubarb crossways over the pastry, top with strawberries, scatter with sugar and bake until pastry is golden and fruit is tender (35-40 minutes). Scatter with candied seeds and serve warm or at room temperature with yoghurt alongside. Best eaten on day of making.|
