As soon as I'm off my diet, I'm going to make this. It's from Leith's Recipe of the Day in the Daily Mail. Notes from the recipe say: blackcurrants are high in vitamin C. And although they can be sharp, that edge is lost in the deliciousness of this crumble. Choose a dish so that the crumble mixture comes to the top, ensuring it browns in the oven. Leith's used 250g hard butter fudge, chopped into small pieces- Sainsbury's Taste the Difference hard butter fudge. The system wouldn't take this descripion.
