I have this problem, please let me know of any remedies or alternate cooking methods.
I love steamed/sauteed baby spinach, but it leaves this kind of coating/film on my teeth. I often experience this with dried cranberries as well.
I cook the baby spinach in a tablespoon of water, then add chopped garlic and EVOO, s&p. Great tasting, but then comes the film! Brushing my teeth helps, but this is just odd. Is there anything I can add to the cooking process--an acid like lemon juice or vinegar?
