I am a newby and have just made my first purees. My white puree is a light green, maybe from not heavily peeling the zucchini? What can I do to fix it now? I don't know how well green, mashed potatoes will go over.
It's probably too late to turn your potatoes back to green, but take heart, it has happened to others before you, and it's almost always that there was still too much skin left on the zucchini. Make sure you've completely peeled all the green off before pureeing. That will leave you with only white to add to your potatoes : )
Enjoy in good health,
