This is lovely served hot as a pudding, or cold as a yummy teatime cake.
3oz (75g) unsalted butter
9oz (250g) light brown soft sugar
10 fl oz (284ml) soured cream
2 medium eggs
3 tsps ground ginger
11oz (300g) self-raising flour
14oz (400g) rhubarb, with the leaves removed and the bottoms trimmed, then cut into chunks
100g caster sugar
Preheat the oven to gas mark 4 (180C).
Grease a round cake tin and line the base with greaseproof paper.
In a food mixer, cream the butter and sugar together. If it looks a bit dry, use a bit of the soured cream and beat again until it’s nice and smooth.
Beat in the remaining cream and the eggs, along with 2 tsps of the ginger. Remove from the food mixer and tip into a large bowl. Gently fold in the flour.
Now tip the whole thing into the cake tin and smooth over the top. Scatter the rhubarb chunks all over the top of the cake – they’ll cover it completely.
Bake for 1 1/2 hours – you can test whether the cake is done by sticking a skewer into the middle. If it comes out with cake mixture still sticking to it, the cake needs another ten minutes or so.
Leave the cake to cool in the tin for ten minutes, then get the tin off and transfer the cake to a cake rack to cool (this can be a bit tricky as with the rhubarb on top you can’t turn it upside down: just work the cake tin off as best you can). Once it’s not too hot to handle, you can lift it up and work off the greaseproof paper, too.
You can serve it just like this, but to make it really posh, make a glaze for the top, too. Gently heat the caster sugar with 3 fl oz (90ml) cold water and the remaining ginger, until the sugar has dissolved. Then bring to the boil and cook for five minutes – it’ll turn into a golden brown syrup. Simply spoon it over the top of the cake and let it cool.
