The pork tenderloin sounds delicious.
I’ve cooked the butter poached potatoes before and they came out all right. The recipe calls for unsalted butter.
Dumb question here but: do you wait until the butter reaches room temperature, then apply the butter over the potatoes before you add them to the bag? I added slices of still cold butter to the bag, sealed it and noticed after cooking that the slices never really melted around the potatoes.
Thanks!
