Potatoes
10.01 cup : 1 cup
Slightly sweet, mash or roast same as potato
10.0
parsnips substitute
for frying.
Cut into matchsticks 6mm thick, parsnip fries crisp at 350°F in roughly four minutes once surface starches form a brittle shell through Maillard browning. The high sugar content (around 4.8g per 100g) means oil temperature should not exceed 360°F or the exterior chars before the interior reaches 200°F. Soak cut pieces in cold water for ten minutes, dry thoroughly, and fry in two stages for hollow-bone-light texture.
top substitutes
adjustment for frying
Potatoes fry crisper than parsnip in roughly the same four minutes at 350°F because their starch shell sets harder and faster. They lack parsnip's surface sucrose, so they brown less; bump oil to 365°F and the salt to 1.2% by weight of the cut potato to compensate for the missing sweetness. Two-stage fry at 325°F then 375°F for hollow texture.
02
Sweet Potato
8.01 cup : 1 cup
Naturally sweet when roasted, similar texture
8.0
adjustment for frying
Sweet potato fries crisp differently — outside browns by minute three at 325°F (lower than 350°F because surface sugar burns above 360°F). Cornstarch dredge (2 tablespoons per pound, five-minute rest) is essential since they hold less surface starch than parsnip. Salt immediately out of the oil while sucrose film is tacky and active for adhesion.
03
Turnips
7.51 cup : 1 cup
Earthy and mild, great roasted
7.5
adjustment for frying
Cup-cut turnips fry in roughly four minutes at 360°F, similar to parsnip. They lack the surface sweetness, so dredge in a 1:1 mix of cornstarch and finely powdered sugar (2 tablespoons total per cup) for a Maillard-equivalent crust. Watch oil temperature carefully past minute three; their lower starch makes them less forgiving of late-stage drops below 340°F.

Beets
7.51 cup : 1 cup
Sweet and earthy when roasted; lighter color
7.5
adjustment for this dish
Beets fry in four to five minutes at 350°F, comparable to parsnip, but their high natural sugar (6.8g per 100g) means oil should not climb past 355°F or the exterior burns sticky. Soak cut sticks in cold water fifteen minutes, dry, then dredge in 1 tablespoon cornstarch per cup before frying.
05
Salsify
7.51 cup : 1 cup
Oyster plant has similar earthy sweet flavor
7.5
adjustment for this dish
Salsify fried in 350°F oil takes three to four minutes for a glassy, brittle exterior similar to parsnip. The flesh oxidizes within two minutes of cutting — drop into acidulated water and dry just before frying. Its starch is closer to parsnip's than potato's; expect the same caramelized snap with slightly more vegetal aftertaste, balanced by salt and lemon zest.
06
Cauliflower
6.71 cup : 1 cup
Sweeter flavor, works mashed or in gratins
6.7
adjustment for this dish
Cauliflower needs a batter to behave like a fry; toss florets in a 1:1 cornstarch-flour batter (3 tablespoons total per cup) and fry at 365°F for four to five minutes. Without batter, the cut surfaces dehydrate before browning. Internal cook is fast (two minutes) since florets are mostly water; drain on rack to preserve the brittle batter shell.
07
Kohlrabi
5.01 cup : 1 cup
Mild and crisp, works roasted or in soups
5.0
adjustment for this dish
Kohlrabi cut into 6mm sticks fries in three to four minutes at 360°F, slightly faster than parsnip due to lower density. Sugar load is half parsnip's, so roll in 2 teaspoons sugar plus 1 tablespoon cornstarch per cup before frying for browning parity. Salt at the rack while glossy at 1% by weight.

Plantain
5.01 cup : 1 cup
Slice and fry, sweet when caramelized

Carrots
