Roast Tomato & Basil Soup

Roast Tomato & Basil soup

Everywhere I look lately I see tomato soup recipes and photo’s. This might be the reason why I was so amped to make it last week, and why my husband was so surprised to find out that I’d never made or eaten tomato soup before. I think it’s the fact that in our high school Home Economics class, the teacher always said you can’t make tomato soup in certain pots, I think it was Aluminium, because the acid in the tomatoes react with the Aluminium and this gives the soup a metallic taste. The thought of that petrified me and I was always too scared to make it. Meanwhile, we only had cast-iron and stainless steel pots and pans at home so I had no reason to really be scared of attempting this soup.

I was also nervous that my soup would taste like Marinara sauce or ketchup…I mean I love both, but I don’t want to dig into a whole bowl of it. So it took a lot of careful seasoning and tweaking to get the flavours to just where I want it. I think using Balsamic Vinegar to roast the tomatoes in made a big difference and gave the soup a lovely rich quality. Also, I used a bit of soy sauce to add body and depth to the soup. There is just nothing like soy sauce when you want richness to something. I didn’t add enough for you to really taste there was soy sauce in the soup, just enough to add the lovely savoriness I wanted from it.

The end result was a soup with a bit of sweetness, saltiness and just the right amount of acidity. It was delicious with the rustic green olive bread I served it with and please excuse the excessive use of cream and balsamic vinegar on top of the soup. I am obsessed with drizzles and swirls, but I am trying to work on this problem, I promise!
