This recipe looked delicious but was much more time-consuming than it suggested and overall was a massive failure. Despite removing every trace of salt from the exterior of the potatoes, they were nearly inedible. Shallots were limp. Chestnuts too dry. Felt like a huge waste of all the salt. Next time I will skip the salt roasting and roast the other ingredients on a cookie sheet. Faster, simpler, no waste, and more likely to have a good result.
