  1. 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.
  2. 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.
  3. 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.

This cake is a winner. Really delicious flavour combination! I put extra juice in the cake and made 1 1/2 times the syrup. a big hit!

I have made poppy seed cakes before, respectively flavoured with almond, orange and lemon. This was my first time baking with grapefruit and I thought it was quite nice. I substituted Greek yogurt for the sour cream, since that is what I had on hand. I didn't make the glaze this time as my husband was anxious to try the cake but next time I will.

Weirdly flavoured, greasy and dense. A cake is no place for a grapefruit!
