Since I bought a food processor my cooking has been revolutionized. It’s nothing but a simple juicer that soon earned space and authority in my kitchen as the author of many smoothies and drinks. This tomato soup made on a windy winter day in London, is only one of the ways I implemented the cheap tool. I am not ashamed to tell you I have even used it to make a ragu (well, my mum in Italy would be ashamed).
Although effortless in principle, a good tomato soup is not easy to make. I’ve experienced a few disasters with most of my attempts leading to sour and/or too liquid soups. We all know how good fresh tomato is: why is it that when cooked and processed to a sauce, tomato brings lots of acidity to the palate (and stomach)?
In short, I was never that lucky to find the perfect sweet tomatoes and I always disliked the taste of my soup.
Then I changed strategy:
I started selecting the right ingredients what I like to call “the unconventional tomatoes”. Those ones pretty soft and very ripe. Those ones you wouldn’t consider because they are too mature and you’d never buy for any other recipe. Long and moisty San Marzano tomatoes would be just perfect, otherwise well ripen tomatoes on the vine would do well too.
Before leaving you to the recipe I’m going to “reveal” one last secret. How I prevent the soup from becoming too acidic. Which would always happen otherwise, no matter the kind of tomato I use, since any tomato juice has a pH of about 4.3, a rather low value (low pH, high acidity).
All types of dairy products produce acids in our stomachs. Cream, butter and milk are among them. Fresh low-fat yogurt is an exception, providing proteins that nourish without producing acids. Here’s then unveiled my secret ingredient: yogurt. Many would choose a sour cream or butter; to make the soup gentle to my stomach I opt for a dense organic yogurt, instead. Try it this way and let me know.
Now off to blend more stuff. What do you use your blender for? If you have any “crazy” idea, please share it with me!
