Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Cold roast beef: Forms the main meat body of the dish, set within the clear jelly.
Beef dripping: Fat used to rub the pan, adding richness to the initial frying.
French gelatine: Sets the stock-and-water liquid into a firm jelly that holds the meat in shape.
Tarragon vinegar: Adds acidity that brightens the flavour of the jelly.

The step that matters

Let the jelly partly set before pouring it over the meat. If the jelly is too warm, it can melt the layer already set and blur the garnish; if it is too cold, it will set unevenly and fail to bind the meat. Pouring it as it begins to thicken lets it settle around the meat and hold the garnish in place.
