The potato is, the oil isn’t..................
But if I use the government approved vegetable oil?! ;)
Honestly though - I wonder if frying in beef tallow might actually be “healthy”
(After it was banned because “fats bad” they discovered that it wasn’t fats per say but the hydrogenization of the fats - like Crisco and shortening that was the real culprit because the processing of the fat changed its structure making it easier to get into the blood stream. Unprocessed fats and natural fat oils (bacon grease) maintain their structure and don’t get into the bloodstream until naturally broken down by digestive processes)
