Soured cream bundt cake with butter glaze
Soured cream makes for a light and moist pretty, ring-shaped cake that's offset by a creamy, crunchy drizzle
Heat oven to 180C/160C fan/gas 4. Butter then flour a 1.5-litre Bundt or ring tin. Beat together the butter and sugar until pale and fluffy. Beat in the eggs, one at a time, followed by the vanilla, flour, baking powder, soured cream, grapefruit zest and juice, and toasted poppy seeds. Scrape into the tin and level it off. Bake for 40-55 mins, depending on the shape of your tin, until a skewer poked in comes out clean. Leave in the tin to cool a little while you make the icing.
Gently heat the caster sugar, butter and grapefruit juice to melt the butter. Bring to the boil, then reduce heat and simmer for 3 mins. Remove from the heat, stir in the zest and cool for about 10 mins until thickened and syrupy.
Turn the warm cake out onto a cooling rack and brush half the glaze over the cake. Spoon the rest over, little by little, so it sinks in.
