salted butter substitute
in stir fry.
Salted Butter coats the wok and conducts heat for a fast Stir Fry sear. The substitute must handle high temperatures without smoking or adding off-flavors.

adjustment for this dish
Unsalted butter has the same 302°F smoke point as salted butter, so keep it strictly as a 15-second off-heat finish on the wok. Add 1/4 teaspoon kosher salt directly to the stir-fry during the high-heat sear (before the butter ever touches the pan) so the seasoning builds on crisp edges; swirl 1 tablespoon cold butter per serving at the end for the gloss coat.

Stick Butter

adjustment for this dish
Stick butter at 302°F smoke point is still a finishing fat, not a cooking fat — never add it while the wok is ripping at 450°F. Salt the protein and aromatics during the sear with 1/4 teaspoon kosher salt, then kill the flame and swirl in 1 tablespoon cold stick butter per serving; the residual heat at 350°F melts it into the glossy 15-second coat without burning.

Margarine

Dairy-free, add pinch of salt

adjustment for this dish
Margarine has a smoke point closer to 360°F thanks to lower milk solids, so it tolerates a slightly hotter wok than butter, but the flavor is waxier on a high-heat finish. Use 1 tablespoon per serving and swirl it in at 380°F (just after flame-off) for a 10-second coat. Most margarines are already salted, so cut the kosher salt on the sear to 1/8 teaspoon to avoid briny aromatics.
technique for stir fry
technique
Salted butter in a stir-fry is a finishing fat, not a cooking fat — its smoke point is 302°F and a properly ripping wok sits at 450°F or higher, so butter added at the start will blacken its milk solids in under 20 seconds and throw acrid smoke. The move: stir-fry aromatics (ginger, garlic) in a neutral high-heat oil first, sear proteins and vegetables to a char, then kill the flame and swirl in 1 tablespoon cold salted butter per serving at the end; the residual thermal energy melts it into a gloss that clings to crisp edges without burning.
6g sodium per tablespoon. Toss for 10 to 15 seconds so it coats every surface while the wok drops to around 350°F.
Unlike pasta, where salted butter builds a slow emulsion with starchy water at 200°F, stir-fry uses butter as a 15-second sizzle-and-coat at the tail end of high-heat cooking, so the butter keeps its flavor instead of breaking into clarified fat and burnt solids.
pitfalls to avoid
watch out
Don't start aromatics like ginger and garlic in salted butter over high heat — the 302°F smoke point is far below the 450°F wok temperature, and the milk solids char to acrid black specks in under 20 seconds.
watch out
Avoid adding butter before the sear stage; any fat that sits in the wok during the initial sizzle will break and smoke, coating vegetables with burnt-dairy flavor instead of clean char.
watch out
Skip added salt in the sauce because 1 tablespoon of salted butter delivers 0.6g sodium off heat at the end, which seasons the final toss without oversalting the crisp edges.
watch out
Don't let the wok drop below 300°F before swirling in butter — too cool and the fat pools around the aromatics instead of melting into a quick, glossy coat.
watch out
Avoid substituting butter for the primary cooking oil; use a high smoke point oil for the flame work and reserve the salted butter strictly as a 15-second finish.
