To me, a turnip is 4-6" diameter, whitish inside where the top was cut off and a distinct purple color blush on the outside of the top. I learned by experiment that a big double handful of fries, not agitated too much, is done in 3 mins 30 sec. The coating is browning just a littleand they are cooked through. I'll admit there some really scuzzy burnt sludge that settle out. Four minutes in the pot and many tip/ends are beginning to burn. Having chicken tonight? Get the oil going and deep-fry branches of sage and oregano for edible garnish. I'm fond of using one or another of the dry rubs which are usually applied to meats going into my big smoker BBQ rigs. 3 hrs at 275 with some apple wood.
