Cold water matters: It helps extract collagen slowly for better body. | No salt now: Season dishes later, stock reduces and can easily over-salt. | Overnight oven method: Perfect if you want hands-off cooking, especially with an AGA or residual heat oven. | Deep colour hack: If your stock looks pale, reduce it further rather than adding extras. | Fridge: Keeps 4–5 days in a sealed jar. | Freezer: Freeze in ice cube trays for instant portions, or in 500 ml tubs for soups and risottos. | Next uses: Turkey pie gravy, leftover turkey soup, risotto base, braised lentils, or enriching pasta sauces.
