I just made soup too!!! French onion soup made with lots of white wine for my husband. I had a glut of white onions and loads of dregs of white wine that I put in one big bottle. Lots of stock, balsamic vinegar sugar salt garlic and pepper and hey presto!! It's pretty good even if I don't say so myself!!!! :-)
My favourites are roasted tomato and red pepper, broccoli and Stilton, pea and ham, sweet potato with red lentil and coconut and cauliflower with almond.
Carrot and Coriander would be my favourite. BUT I appear to be well-known for leek & potato, have made it for several village 'Do's' and seem to be condemned to it forever. Basically, I follow Delia's recipe, which you can look up - perhaps a touch of cream makes the difference.
