How to make a white cream sauce
Peel and thinly slice the shallot. Peel and roughly chop the garlic. Strip the thyme leaves from the stalks. Sweat the shallot with a little butter for 1 minute before adding the garlic, thyme and white wine. Simmer and reduce by half. Add the double cream and bring to the boil. Pass the sauce through a sieve and season well.
