You created a compelling story about the wonders of the root vegetable and I can't help but to try it. I will check my local markets for it. As I said, I can't recall seeing that vegggie but then I may have passed over them. I promise I won't use Karo syrup but I will tell you as a barrio boy I was raised on the stuff.
I'm pleased to know that you're planting the tree as a memorial to your mother. That's thoughtful and you will be reminded of her as you step out of your home.
