Spaghetti with sour tomato purée

As the tomato purée turned sour I turned sour, because it tasted sour.

Bizarre!

The tomato purée looked proper and couldn’t find any trace of mould or bubbles. And it tasted good but sour. The acidity was the only thing that mattered.

In addition, it is more sour when cooked.

Here is my tomato spaghetti.
