The Gamja Project (14)
In this series, I cook potato dishes using freshly harvested gamja gifted to us from a neighboring farmer at the cabin (for more background and related posts, see THE GAMJA PROJECT).
For this final installment, I made fries from scratch, the first time in my life (as far as I can recall). I adapted parts of the recipe “Classic French Fries” from Cook’s Illustrated: The Science of Good Cooking.

The main technique that I learned from the recipe was tossing the raw potatoes pieces in cornstarch and letting them sit to form a gluey coating, which is supposed to make the fries extra crispy.

Although I’m well-versed in the flavor of foods fried in rancid oil (see for example 11.037 Chickenjoy) – based on my time in the Philippines, where they love frying things but don’t replace oil as often as they should – I was unaware on the other end of the spectrum that brand new oil is less-than-optimal.

According to the book, frying oil works has 5 stages: break-in (too fresh to fry well), fresh, optimal, degrading (on the way to spoiling), and runaway (dark, smelly, and prone to smoking). Oil that is too fresh can’t penetrate the barrier of moisture that surrounds food as it fries. Through repeated use, the level of free fatty acid that helps penetrate the moisture increases from about 0.03-0.05% in fresh oil to 8-10% in runaway oil.

From the outset, I was at a disadvantage on the oil front. First, all I had on hand was canola oil, which the book had tested for making fries and found to produce “bland, almost watery fries.” (The book recommends peanut oil, which isn’t sold in Korea.) Next, the oil was at the “too fresh to fry well” break-in stage, straight out of the bottle. I happened to have a couple cups of leftover extra virgin olive from the patatas bravas (see 14.190 Patatas Bravas) – though of course olive oil is generally advised against for deep-frying because of its relatively low smoke point – but the book does suggest that mixing used oil with new oil can help. And finally, the book calls for the addition of a 1/4 cup of bacon fat to amp up flavor, and I just happened to have 2 frozen slices of bacon, which I rendered to produce about 1 tablespoon, but I doubt that it made much difference.

According to the recipe, I deep-fried the potatoes in 2 batches at 325F (160C) for 4-5 minutes, then rested them for 10 minutes, which turned out fine. Cranking up the heat to 350F (175C) , I deep-fried them again – but some of the potatoes starting browning almost instantaneously, so I had to scoop them out before they burned. I turned down the heat back to 325F (160C) and added the second batch, which cooked evenly for the first minute but then some of the pieces started browning while others didn’t. I attribute the difference to uneven coating of corn starch.
I dedicate the dish to my Belgian friend EE (see 13.172 Gamja Twigim (Frietjes))

The project is now done with the initial batch of potatoes. Still have a handful of leftover skins, which I’ll make (tomorrow?) as a bonus dish.
