General Recipe for Milk-vegetable Soups
Ingredients
Directions
Make the soup
In a saucepan, thicken the milk with the flour as you would for milk gravy.
Add the butter, salt, and the prepared vegetable to the thickened milk.
If the soup is too thick, thin it with additional milk or water.
Serve
For serving, add a pinch of baking soda to prevent the milk from curdling.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Milk
- Forms the liquid base of the soup and gives it a creamy body.
- Flour
- Thickens the milk as it heats, giving the soup body and a smooth texture.
- Butter
- Adds fat for richer flavor and a smoother mouthfeel.
- Thoroughly cooked vegetable
- Supplies the main flavor and solid texture of the soup.
The step that matters
Adding baking soda for serving. Milk curdles when it is heated or when acidic ingredients are present. Baking soda raises the pH slightly, which helps keep the milk smooth. Using too much can leave a soapy or bitter taste, so only a pinch should be added.
