This traditional, thrifty, Tuscan soup is a delectable mishmash of vegetables, beans, cheese and stale bread, making it perfect for using up all sorts of odds and ends
The Guardian – “Much complicated nonsense is talked about this Tuscan soup”, said the late chef Alastair Little, of a dish that is traditionally made from leftover minestrone and stale bread. As with so many zero-waste dishes, it doesn’t do to be too prescriptive, but if you do want to make ribollita (literally, “boiled over”) from scratch, a few pointers might be helpful.
The vegetables
Like many Italian dishes, ribollita starts with a soffritto of fried carrot, celery and onion (Katie Caldesi uses red onion as well as yellow in her Italian Cookery Course, which give her soup a pleasant sweetness).. It also tends to be very heavy on the greens; cavolo nero would be my first choice, for its robustness of flavour and texture, but if you have another sort of cabbage, chard or leafy green, simply adjust the cooking time accordingly.
I also like the silkiness of Caldesi’s leek, and have added some seasonal diced squash, too, though play around with whatever needs a home.
The aromatics
Add garlic to the beans as they cook, as in Lori De Mori’s take in Beaneaters & Bread Soup. Though my testers and I can’t taste Alvaro Maccioni’s root ginger, we love Angela Hartnett’s fennel seeds and chilli, but herbs such as thyme, rosemary or sage also make fine additions.
The starch
Cannellini beans are common in ribollita, but any beans will do. If you cook them from dry, add a strip of kombu to make them more digestible. De Mori and Maccioni puree some of the beans and stir them into the broth along with the mandatory bread, to thicken it.
Caldesi and De Mori both bake their ribollitas, but I’m going to stick mine under the grill to crisp the top, so I don’t have to turn on the oven for too long.
The extras
Add stock, or a dash of red wine (as suggested by James Ramsden in his new book, Every Last Crumb) if you happen to have some at the bottom of a bottle. Parmesan rinds (or those of another hard cheese) are rarely a bad call in soup, and popping in some sausages, as Valentina Harris recommends in her Italian Regional Cookbook, will help stretch a little meat a very long way. Which is what ribollita is all about.
