Ideas for jicama, let's see...
There's Joz's poppyseed cake for one!
I think Alissa has a really nice raw 'potato' salad made with it. I think you've got her book but I've posted it here
Diana Stoevelaar also has a really nice jicama salad recipe, Mexican style. See this thread
Finally, there's the 'Jica-Rice Fresh' in Carol Alt's new book, "The Raw 50".
I just processed jicama in the FP until rice like. Then added chopped red onion, red and yellow pepper, cherry tomatoes, garlic, black pepper, olive oil, cumin and salt. Yum! Yum!
Can't wait to hear about how you like the garlicky toasts!!!
