Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Veal
- Provides the meaty flavour and body that the sauce is built on.
- Bacon
- Adds fat and savoury flavour to the stock as it cooks.
- Rice flour
- Thickens the liquid as its starch swells with heat.
- Veal stock or water/milk
- Forms the liquid base that the flour thickens and the flavourings infuse.
- Cream
- Adds richness and a smooth, velvety texture to the finished sauce.
The step that matters
Mix the rice flour with water until smooth before adding it. Dry or poorly mixed flour forms lumps that stay hard in the hot liquid. Dispersing the starch in water first lets each granule swell evenly, so the sauce thickens smoothly.
