Sadly, this post could also be titled New Recipes Don't Always Work.
Kyotic Kitchen. They looked delectable, and I gave them a whirl (completely followed the instructions).
The temperature setting for the oven looked a little low to me, but I followed in the instructions. At what was supposed to be the end of cooking time, the liquid was nowhere near evaporated and the potatoes were still hard.
A couple hours later, the liquid was gone but the potatoes were rubbery and still not caramelized on bottom. I'm pretty sure that low oven temp was the culprit.
While I intend to try this again with less liquid and a higher cooking temp, I post it here as a reminder that experimenting in the kitchen doesn't always end with the desired results. Keep a backup on hand and keep playing with recipes! At least the fox who eats our compost dined well that night...
