Corn Oil

Another neutral frying oil

soybean oil substitute
in stir fry.
Stir Fry uses Soybean Oil for clean fat that lets other flavors come through. With wok temperatures often exceeding 400°F, the substitute needs a refined smoke point in the same range (~440–450°F) so it won't break down and deposit bitter acrolein on the vegetables before they char.

adjustment for this dish
Swap 1:1 by tablespoon. Corn oil's 450°F smoke point is within 10°F of soybean and carries aromatics like ginger and garlic through the 15-second sear without breaking down. Preheat the wok 2 minutes on high heat; toss every 8-10 seconds for the same char.
02
Vegetable Oil
10.0best for stir fry1 tbsp : 1 tbsp
Typically soybean-based already; interchangeable in frying, baking, and dressings with no flavor difference
10.0
adjustment for this dish
Swap 1:1 by tablespoon. Vegetable oil blends usually include soybean and sit at the same 460°F smoke point, so the quick sear phase and aromatic release behave identically. 2 batches beats crowding; the wok recovers heat within 20 seconds between drops.
03
Canola Oil
10.0best for stir fry1 tbsp : 1 tbsp
Neutral flavor, similar properties
10.0
adjustment for this dish
Swap 1:1 by tablespoon. Canola oil's 400°F smoke point is 60°F lower than soybean — preheat the wok only 90 seconds instead of 2 minutes to avoid breaking the oil into acrid smoke. The quick sear and aromatic release hold at that slightly lower thermal threshold.

Sunflower Oil
10.01 tbsp : 1 tbsp
Light neutral oil for any cooking
10.0
adjustment for this dish
Swap 1:1 by tablespoon. Sunflower oil's 440°F smoke point handles high heat and ginger-garlic sizzle cleanly. Preheat the wok 2 minutes; toss aromatics for 15 seconds before protein. The char on vegetable edges tracks soybean oil within a visible shade.
05
Peanut Oil
6.71 cup : 1 cup
Similar smoke point, widely available
6.7
adjustment for this dish
Swap 1:1 by cup. Peanut oil's 450°F smoke point and nutty flavor are purpose-built for stir-fry and actually upgrade the dish. Preheat the wok 2 minutes; the sizzle on ginger and garlic pops within 10 seconds, and the quick sear on protein reads identical to soybean oil.
technique for stir fry
technique
Soybean oil's 460°F smoke point lets it carry aromatics like ginger and garlic through the 30-second sear phase in a ripping-hot wok without breaking down into acrid smoke. Heat 2 tablespoons oil in a wok preheated 2 minutes over high heat until it shimmers and just begins to wisp; drop aromatics in for 15 seconds, then protein, then vegetables in order of density.
Keep everything moving — toss every 8-10 seconds so nothing scorches against the metal but every piece gets char and crisp edges. Total cook time from first sizzle to plating is under 4 minutes.
Unlike pasta where oil emulsifies with starch water at 180°F and clings to noodles, in stir-fry oil is a thermal transfer medium that flash-sears surfaces and carries flame-kissed aromatics. Do not crowd the wok; cook in 2 batches if needed so the pan recovers heat between drops.
pitfalls to avoid
watch out
Don't drop aromatics into cool oil — ginger and garlic need 460°F smoke point oil to sizzle and release flavor in 15 seconds; cool oil steams them bland.
watch out
Avoid crowding the wok; 2 batches beat one because crowding drops the thermal bank below the sear point and food stews instead of getting char edges.
watch out
Use high heat from start to finish — dropping to medium loses the smoke point advantage and the oil breaks down into bitter notes.
watch out
Toss every 8-10 seconds so nothing welds to the metal; static food scorches against the wok and turns acrid under direct flame.
watch out
Preheat the empty wok 2 minutes before adding oil — cold metal absorbs heat from the oil and you lose the quick sear that defines stir-fry.
