Butter
4.0best for sauce1 cup : 1 cup
Adds dairy flavor and slight saltiness; firmer texture makes flakier pie crusts and pastries
4.0
margarine substitute
for sauce.
Sauce work brings margarine into 140-180°F emulsions where its emulsifier package (usually lecithin plus mono- and diglycerides) stabilizes fat-in-water mixtures better than pure butter. Its 80% fat delivers coating viscosity around 1500 cP after a brief reduction. Subs rank on emulsion stability at 160°F over 30 minutes, whether the fat splits under acid at pH 3-4, and how the sauce holds between plating and service in a restaurant line where re-warming is common.

adjustment for sauce
Butter at 1:1 cup for margarine in sauce work — classic beurre monté emulsifies at 140-180°F into any warm liquid over 5-10 minutes. Mouthfeel is silkier from milk solids. Splits above 190°F; re-emulsify by adding 1 tsp cold water and whisking off-heat. Holds 30 minutes on a warm line at 160°F before breaking.
02
Coconut Oil
6.7best for sauce1 cup : 1 cup
Dairy-free, solid at room temp, slight coconut taste
6.7
adjustment for sauce
Refined coconut oil at 3/4 cup per cup margarine emulsifies into Thai and Caribbean sauces cleanly — coconut milk sauces welcome the added fat. Stable at 160°F for 40 minutes. Holds emulsion under acidity (pH 3.5 lime) slightly better than butter due to saturated fat profile. Virgin brings tropical flavor; refined stays neutral.
03
Olive Oil
6.7best for sauce3/4 cup : 1 cup
Use less, best for savory baking and cooking
6.7
adjustment for sauce
Olive oil at 3/4 cup per cup margarine in sauce work emulsifies via lecithin or egg yolk rather than milk solids — works in hollandaise variations, aioli, and Italian pan sauces. Holds at 160°F for 25 minutes before breaking. Pair with lemon, garlic, and a splash of pasta water for a stable 1400 cP coat.

Whipped Butter
6.73 tbsp : 2 tbsp
Reduce amount, whipped is aerated
6.7
adjustment for this dish
Whipped butter at 1.25 cups per cup margarine in sauce applications — the incorporated air integrates quickly but makes the sauce lighter and less coating at 1200 cP versus stick butter's 1500 cP. Better for quickly-served à-la-minute sauces than sauces held on a line for 30+ minutes at 160°F.
05
Salted Butter
5.01 tbsp : 1 tbsp
Dairy-free, add pinch of salt
5.0
adjustment for this dish
Salted butter at 1:1 cup for margarine in sauce — reduce added salt by 1/4 tsp per stick. Emulsifies cleanly at 160°F for 30 minutes before splitting. Best in pan sauces where you're already seasoning with salt-forward aromatics. For delicate sauces where salt control is critical, swap to unsalted butter.
06
Sour Cream
4.01:1
Adds tang and moisture; use 1:1 in baking for tender crumb, not for spreading
4.0
adjustment for this dish
Sour cream at 1:1 cup in sauce work is a different sauce category entirely — not fat emulsion but acid-dairy thickening at 140-160°F. Adds 19% fat plus yogurt-like tang (pH 4.5) to pan sauces for stroganoff, Hungarian paprikash, and Mexican crema-based sauces. Splits above 180°F; keep gentle.
07
Ghee
6.71 cup : 1 cup
Richer flavor, no water content so reduce by 1 tbsp
