A cost rule that survives inflation

Ingredients for 2

- 175 gripe tomatoes
- 112.5 gwhite beans

- 50 mlvegetable stock
- 30 mllow-fat milk

Method
Each step includes heat, a visible cue, and a recovery.

Step 1 · follow the visible cue
Prepare the measured ingredients
Start with accurately portioned ripe tomatoes, white beans, and carrots. Match the listed amounts, prepare each for its own cooking time, and keep wet components away from ingredients that need a dry surface.
Look for: Nothing should enter the pan until ripe tomatoes, white beans, and carrots are evenly prepared, accurately measured, and free of unintended surface water.

Step 2 · follow the visible cue
Build the defining flavour
Wake up the characteristic aromas in onion, vegetable stock, and low-fat milk. Add them in a deliberate order so strong aromatics soften without burning and delicate notes remain noticeable in Tomato Soup.
Look for: The flavourings are correctly handled when onion, vegetable stock, and low-fat milk smell rounded and remain recognisable, with no black flecks, raw spice aroma, or separated fat.

Step 3 · follow the visible cue
Cook with controlled heat
Cook only as far as needed to roast tomatoes and carrots, blend with beans and stock, and stir milk in over low heat after the acidity mellows. Regulate heat and exposed moisture throughout this stage instead of correcting the texture later with extra oil, sugar, or sauce.
Look for: End the main cook as soon as the soup is smooth and red, coats a spoon lightly, and shows no milk curds or watery edge. Check the thickest or coolest part rather than judging only the browned surface.

Step 4 · follow the visible cue
Finish and verify the texture
Once the heat is off, bring in basil and black pepper. Stop when the soup is smooth and red, coats a spoon lightly, and shows no milk curds or watery edge, allow only the rest required for the structure to settle, and divide Tomato Soup evenly into two portions.
Look for: Portion the recipe once Tomato Soup holds its intended shape and the soup is smooth and red, coats a spoon lightly, and shows no milk curds or watery edge; no excess liquid, fat, or loose coating collects around the serving plate.
