I use the term recipe in the loosest sense, as you can probably toss the potatoes with whatever seasoning floots yer boot. I did use the olive oil & mustard, but didn’t have garlic salt. I added onion powder & Tony Cacheres seasoning instead. No zester either, so no lemon zest. The taters came out nicely crisp and creamy. Keeper, at least with regard to time & temps.
