Sweet milk sounds like a dessert ingredient until you read it beside sour milk. The term often describes the milk's condition rather than added sugar.
What to understand
In the supplied collection, sweet milk contrasts with sour milk. That distinction can affect recipes using soda or baking powder. Do not add sugar merely because the word sweet appears, and do not assume sweetened condensed milk is an equivalent. Read the full ingredient list and method before deciding what a dated term means.
A practical checklist
- Look for contrasting terms elsewhere in the same edition.
- Choose ordinary milk when that is the intended meaning.
- Treat concentrated and sweetened dairy products as different ingredients.
A mistake to avoid
Avoid adding an unlisted sweetener to correct a name you misunderstood. That changes the formula instead of clarifying the language.
Is sweet milk the same as condensed milk?
Not in this context. Condensed milk is concentrated and often sweetened. The old term generally distinguishes unfermented milk from sour milk; it is not a direction to use a canned concentrated product.
