How do you make garlic pasta sauce from scratch?

To make spaghetti saucecook garlic in butter and olive oil over medium-low heat just until the garlic is soft but not browned. Stir in the parsley or basil and cook for 2 minutes (stirring constantly) until the herbs are limp but still green.

Does roasting tomatoes reduce acidity?

Tomatoes become more acidic as they cook longer, so reducing the cooking time to the least amount possible can help keep the acid level lower. Sauces and other dishes that require long simmering may make this difficult, but it is recommended that you don’t cook tomatoes for longer than 1 ½ hours.
