What each ingredient does
- Onions
- Provide the main body and sweet, mellow flavour of the sauce as they soften.
- Sweet cream
- Adds richness and moisture, letting the chopped onions stew into a smooth, creamy sauce.
The step that matters
Boiling the onions until tender. Onions that are not fully softened stay firm and sharp and will not blend into a smooth sauce. Cooking them thoroughly breaks down their cell walls so they melt into the cream.
