Real Onion Sauce

Step 1

Dice your onion and then gently fry in the butter to "just" soften, over a medium heat - Do not over cook, you are just releasing flavour...About 3 or 4 minutes should do it.

Step 2

Now add your flour (and possibly a little more butter) to make a "Roux". Using a flat wooden spoon or a whisk "cook off" the flour stirring/whisking constantly. Watch things don't catch and burn on the bottom of the pan - Just make sure you keep things moving! I find using a flat silicone spatula works a treat. About 2 minutes should be fine here...

Step 3

Now add your milk and gently bring to the boil and then immediately turn the heat right down to a simmer - keeping stirring (Do not let it catch on the bottom!) TIP: If you've used too much flour you may need to add a little more milk...

Step 4

When your sauce has thickened add your double cream and season with salt and white pepper (I like to chuck in a nob of butter at this stage too...;¬)
