Milk adds creaminess to soup without the heaviness of cream. The sub should not curdle when heated.

adjustment for this dish
Evaporated milk resists curdling far better than fresh milk because its proteins are already partially denatured from the canning process — it holds up to a gentle simmer at 185°F for 3-4 minutes. Use 1/2 cup evaporated plus 1/2 cup stock per cup milk; the concentrated solids give soup noticeably more body and round mouthfeel.

Dry Milk
7.5best for soup1/3 cup : 1 cup
Reconstitute 1/3 cup powder in 1 cup water; shelf-stable pantry swap, slightly cooked flavor
7.5
adjustment for this dish
Dry milk whisked straight into hot broth forms lumps; instead, whisk 1/3 cup powder into 1 cup of warm (not hot) stock, then stir the slurry into the simmering pot off the heat. Its high protein concentration thickens soup subtly, letting you reduce the flour roux by 1 tablespoon per quart while still achieving creamy body.

Cream
7.51 cup : 7/8 cup
Richer and thicker; use half cream plus half water to match milk's body in sauces and baking

adjustment for this dish
Cream's 36% fat resists curdling well above milk's 180°F threshold — you can simmer it at 190°F for 5 minutes without breaking. Use 7/8 cup cream per cup milk for extra body, but cut any added butter by 1 tablespoon per quart to avoid a greasy skim on the surface, and season salt at the very end since cream masks salinity.

technique for soup
technique
Soup uses milk as a finishing body-builder: stirred in during the last 5 minutes of a simmer, it brings velvety mouthfeel without the 36% fat punch of heavy cream. The catch is that milk's whey proteins denature and curdle above 180°F, especially in the presence of acidic aromatics like tomato, wine, or lemon.
Unlike cake batter where milk blends cold into flour, soup must accept milk into a hot broth already seasoned with salt, bay, and sautéed aromatics — any one of which can tip the pH and break the emulsion. Temper first: whisk 1 cup of hot stock into 1 cup of milk off the heat, then return the mixture to the pot on low, holding between 160-175°F and stirring constantly for 3 minutes to let the starch from a flour-based roux (typically 2 tbsp flour per quart) coat the milk proteins and prevent breaking.
Skim the surface, season salt AFTER the dairy goes in to avoid over-salting the reduced body, and do not boil once milk is in the pot — a rolling boil splits the soup within 30 seconds.
pitfalls to avoid
watch out
Don't boil soup after milk goes in — above 180°F the whey proteins denature and curdle into visible flecks that no amount of blending will smooth back into the broth.
watch out
Avoid adding milk to an acidic base (tomato, wine, lemon) without first buffering with a flour roux (2 tbsp per quart); the acid drops pH below 5.6 and splits the dairy on contact.
watch out
Reduce salt before the milk goes in; simmering dairy concentrates the seasoning and a broth that tasted right at 20 minutes reads over-salted once the milk reduces by 15%.
watch out
Skip stirring the pot vigorously after the dairy addition — aggressive agitation breaks the emulsion; use a gentle figure-eight stir to keep the body smooth.
watch out
Don't reheat leftover milk-based soup over high heat; warm it to 160°F over low, stirring constantly, or yesterday's velvety body will break into a grainy mess.
