Your signature method

The short answer

A recipe is one cook's notes from their own kitchen. You now know the job of each step: salt turns flavors up, acid cuts through richness, fat carries aroma, and browning builds depth. So you can swap, scale and improve a recipe instead of only following it.

Scale recipes with care

Doubling a recipe is arithmetic, but cooking it changes the physics. Twice the food in one pan means crowding, so cook in batches. Big pots take longer to heat and reduce, and salt and strong spices go in by stages, with tasting.

From recipes to reasons

You came for recipes and you leave with reasons. Salt, acid, fat, heat, browning and balance are your dials, tasting is your instrument, and a fair test is your method. Pick a dish you love, change one thing, and write down what happens.

Test yourself

Questions from the interactive lesson, with the answer and the why.

A recipe calls for lemon juice and you have none. What is the best swap?

A splash of vinegar, added bit by bit. Vinegar is also an acid. Add it slowly and taste, since strengths differ.

True or false: You can swap any ingredient for another as long as you use the same amount.

False. Ingredients have different jobs and strengths, so swaps work by role and need tasting.

What went wrong? You double a stir-fry recipe and pile everything into the same skillet. It comes out gray and watery.

Twice the food went in the same pan, so it steamed. Extra water pooled and held the pan near 100°C (212°F). Cook in batches.

Fill the blank: When you scale a recipe up, add the salt in ___ and taste between them.

When you scale a recipe up, add the salt in rounds and taste between them. Small rounds with tasting stop you at the right point.

Your soup improves each time you tweak it. How do you make it truly yours?

Record each change and its result. Notes show which changes helped, so every batch builds on the last.

True or false: A signature dish can start as somebody else's recipe that you changed one step at a time.

True. Most signature dishes begin as someone else's recipe, changed one step at a time.
