How to Measure Water & Milk Accurately
Liquid measuring cup on a flat counter, reading the bottom of the meniscus at eye level — never the edge where liquid climbs the glass. Water and whole milk both land at 240 g per cup (density ≈ 1.0), which makes them the calibration pair for every other liquid: learn this one and you can sanity-check the others.
Storing Water & Milk & Common Substitutes
Storage
Milk: refrigerated at or below 4°C and used by its date — smell is a fair final check, but off milk curdles when warmed. Water needs nothing. For baking, cold milk straight from the fridge is fine; yeast doughs prefer it lukewarm (37°C) to wake the culture.
Substitutions
Water and milk interchange 1:1 in most bread and pancake recipes — milk adds browning and softness, water gives a crisper crust. Buttermilk substitute: 1 cup milk plus 1 tablespoon lemon juice or vinegar, rested 10 minutes (weighs the same 240 g but reacts with baking soda differently — reduce baking powder).
