No no no! The cam system operating the chronograph functions of the 861 is best fried in oil with unsaturated fat levels of at least 50%. Coconut oil would be my recommendation. If that’s hard to find in your area you’ll probably be ok using a half and half mixture of beef tallow and ghee.
Depends on planned cooking temperature, if below 325f/163c then let’s go olive, above I’ll reach for canola. No sunflower, that’s too expensive and only used for PP and the like.
