Making Tomato Sauce from Scratch

I’ve always dreamed of making tomato sauce from scratch. It’s not that I dislike store bought tomato sauce. I like it very much. But it’s expensive and we always seem to run out.

This summer, the garden is overflowing with tomatoes. I haven’t seen this many tomatoes in a long time.

All of the ‘experts’ say that you can’t make tomato sauce from regular beefsteak tomatoes. Well, I experimented with several recipes and guess what? You CAN make tomato sauce with beefsteak tomatoes. In fact, any garden tomato works well when making tomato sauce from scratch!

Tomatoes to Use

The best tomatoes to use to make tomato sauce or spaghetti sauce are paste tomatoes, such as the Hungarian paste tomato, shown below.

When choosing tomatoes for sauce, look for ‘meaty’ ones with little juice inside. The more juice in the tomato, the runnier the sauce. That’s why cookbooks recommend paste tomatoes. These tomatoes have a higher flesh to water content and cook down into better sauce.

Fire Roasting Adds Flavor

Here’s the secret: fire roasting.

Fire roasting means cooking tomatoes in the oven or roasting them at a very high temperature. They brown or blacken around the edges and sometimes crisp up, but when blended into sauce, they taste great. The oven roasting process also cooks out a lot of the extra moisture so that when you are making tomato sauce from scratch it doesn’t come out too runny (although I did drain off some of the excess water).
