- If you want a thin sauce, then make sure you use a blender to blitz it. You can use a handheld blender or a standalone. I find using a handheld blender much easier.
- Some people love to add wine to their marinara sauce, but it’s important to keep in mind that it might not cook as well in a slow cooker. You may find there is a bitter wine aftertaste to the sauce by the end of cooking. If you decide to add the wine, then leave the balsamic vinegar out of the sauce.
- The sugar isn’t needed, but it does help remove some of the bitterness from the tomatoes.
- Using the balsamic vinegar helps add a bit more depth to the sauce. It can be left out if you don’t have any or would prefer not to add it.
