What each ingredient does

Cucumbers: The main vegetable that is firmed and flavoured as it soaks in the brine.
Coarse sea salt: Draws water out of the cucumbers and seasons them, helping preserve texture during soaking.
Turmeric: Gives the pickles their yellow colour and adds a earthy aroma.

The step that matters

Heating the mixture to 140°F (60°C) after adding salt and turmeric. Each soak is heated in steps, so the temperature must be reached and held for the full soak time. Raising it too quickly or skipping the staged warm-ups can soften the cucumbers unevenly and affect how the salt and colour penetrate.
