Bone broth is a versatile, nutritious base made simply by boiling marrow bones in water for a long time. To get the maximum nutritional punch, you add a teaspoon or so of apple cider vinegar and simmer the bones over low heat for around twenty-four hours.
To do this on the stovetop would mean someone staying awake all night to monitor the pot and top up the water. In addition, it would require a lot of electricity. That’s why a slow cooker is a much better tool to use when making this broth.
All you do is to add the bones, cover them in water, add a bit of apple cider vinegar and you are all set. Cook them on high for an hour and then switch down to low and leave it until the next day.
It’s not difficult to get right if you have a decent quality slow cooker. In this review, we’ll go through the top options on the market today.
