Quick cauliflower and potato curry

I fancied something simple and veggie last night, so a light curry seemed to be the thing.In hindsight, I should have used a recipe, rather than faffing and experimenting. The dollop of yogurt at the end was a definite mistake, for instance, but the flavours shook out ok.I fried an onion off with the florets of cauliflower, adding ginger and garlic, and chilli as the onion looked like it was heading for done. Then I threw in some spices, which is the point at which i really should have grabbed a notebook. I';m fairly sure it was about a teaspoon each of cumin and mustard seeds, and tumeric; along with a pinch of fennel seeds, some smoked paprika, fenugreek, and cinnamon. Were I guessing, I'd say about half a teaspoon each of those last three.Fry the spices, throw in a couple of chopped tomatoes, diced potato, and some stock, then simmer until broadly functional.I decided to go with a splodge of yogurt to thicken slightly. It didn't work, as you can see from the pictures.It would have benefited from something on the side, I think, or perhaps the addition of spinach.Oh well - lessons and what have you.
