Skim Milk

Thinner and less protein; works in cereal and baking but coffee will taste watery

in bread.
In Bread, Soy Milk provides protein and body that shapes the dough and crumb. Its roughly 3% protein content supports gluten development alongside wheat flour, and its water content hydrates the dough; a swap must supply comparable hydration and at least modest protein so the crumb doesn't turn crumbly or dense.

adjustment for this dish
Skim milk's 3.4% protein matches soy's 3% closely, so gluten and crumb behave similarly. The lack of fat means a crisper crust — if you want a softer crust, brush the loaf with butter in the last 5 minutes of oven spring.

1% Fat Milk
6.7best for bread1 cup : 1 cup
Dairy-free, similar consistency
6.7
adjustment for this dish
1% fat milk adds 1g fat per cup (vs soy's 2g), slightly softening the crumb and extending shelf life by a day. Scald to 180°F and cool to 90°F before yeast; this deactivates enzymes that would otherwise weaken gluten knead.
03
Coconut Milk
5.0best for bread1 cup : 1 cup
Use carton type not canned for drinking
5.0
adjustment for this dish
Coconut milk's 20%+ fat content enriches the crumb into a pillowy soft sandwich loaf. Use the thin part only and scale fat in the recipe down 1 tbsp per cup; the yeast ferments normally but the crust browns 10°F hotter.

Kefir
5.01 cup : 1 cup
Dairy-free, add lemon juice for tang
5.0
adjustment for this dish
Kefir's acidity pre-ferments the dough, giving sourdough-adjacent tang without a starter. Reduce proof time by 15 minutes — the acid relaxes gluten faster, so shape when the window pane test just barely passes rather than fully.
05
Goat Milk
5.01 cup : 1 cup
Slightly tangy dairy milk; not plant-based, similar thin body works in coffee and baking
5.0
adjustment for this dish
Goat milk has 3.5% protein (vs soy's 3%) and 4% fat — slightly richer crumb with a tangy finish. Warm to 95°F for autolyse and the dough proofs fully in 60 minutes; the crust caramelizes a shade darker from the extra lactose.

technique for bread
technique
Soy milk contributes roughly 7g protein per cup, which strengthens gluten networks and gives bread crumb a slightly denser, chewier bite than water-hydrated loaves. During autolyse, combine flour with warmed soy milk (90-95°F) and rest 30 minutes before adding yeast and salt — this hydration window lets soy protein hydrate fully so the window pane test passes after 10-12 minutes of kneading.
Unlike soy milk in biscuits, where kneading is forbidden, bread demands aggressive kneading to build elasticity. Proof at 78°F for 60-75 minutes until doubled, then shape and score with a lame 1/4 inch deep before oven spring.
Soy milk's sugars caramelize at 330°F, giving a deeper-brown crust than water doughs; drop oven temperature 15°F or pull 3-4 minutes early if you see the crust darkening past mahogany. Pan of steam in the first 10 minutes keeps the crust pliable for full oven spring; remove the steam tray at the 10-minute mark so the crust can set crisp rather than gummy.
pitfalls to avoid
watch out
Don't scald soy milk over 180°F before adding to dough; this denatures the proteins that strengthen gluten and weakens oven spring.
watch out
Avoid cold soy milk straight from the fridge — yeast slows below 70°F, stalling the proof past the 60-75 minute target window.
watch out
Reduce added sugar by 1 tsp per cup if your crust browns past mahogany before the crumb reaches 200°F, since soy's sugars caramelize fast.
watch out
Don't skip the autolyse rest; without that 30-minute hydration, gluten development during knead takes twice as long to pass the window pane test.
watch out
Avoid slashing shallower than 1/4 inch when you score — shallow cuts seal shut in oven spring and the loaf splits its own side open instead.
