I've had a look around to see if Delia's recipe is on the web, but it isn't so I can't provide a link, and naturally copyright means I can't reproduce it here, but it's very simple. For two people I boiled 5 eggs and set them aside to cool. (Here's a tip - after cooking, crack the shells all over then place the eggs in a bowl of cold water to cool. When they are cold, they will be really easy to peel). When cold, I peeled and halved them.
Then I cut half a cauliflower into large florets and boiled them until only just cooked, then drained them over a jug and saved the liquid.
I fried an onion in oil and butter, adding garlic when it was almost cooked. Then blended in flour and some spices - I used ground coriander, chilli and turmeric, but you could use your own blend or a ready-mixed curry powder- cooked for a minute and gradually blended in enough of the cauliflower water to give a thick sauce. I mixed in some natural yoghurt and a spoonful of mango chutney, then added the eggs and cauliflower back to the pan and simmered very gently until the eggs and cauliflower were heated through.
With hindsight, I could have made this even more "English" by adding a handful of sultanas along with the egg and cauliflower. And maybe sprinkled some desiccated coconut over the top. Hell, I could even have served it with chips!
