How to make tomato jam
To make the tomato jam, start by preparing the tomatoes. Halve and remove the cores and seeds from 15 Roma tomatoes. Place the chopped tomatoes in a food processor and pulse until they are broken down into small, chunky pieces. Set the chopped tomatoes aside.
Next, caramelize the onion. Finely dice ½ cup of yellow onion. Melt 1 tablespoon of unsalted butter or ghee in a saucepan over medium-low heat. Add the diced onion and cook, stirring frequently, until very soft and deep golden brown, about 20 minutes. The low heat is important to slowly bring out the natural sugars in the onion without burning it.
Once the onion is caramelized, it's time to start the simmer. Add the chopped tomatoes to the saucepan along with the remaining jam ingredient. Allow the jam to simmer gently over medium-low heat, stirring occasionally, for 1 ½ to 2 hours until thickened and reduced by about half. The longer simmer time allows the flavors to develop fully. Remove from heat and enjoy!
