Gordon Ramsay’s lemon butter sauce is a French beurre blanc built by reducing vinegar with shallots and garlic until concentrated, then whisking in cold butter piece by piece until the sauce turns thick and glossy. This version comes from his Uncharted cookbook, where he pairs it with grilled salmon in the Iceland chapter, and takes about 15 minutes.
What makes this worth writing about is that Uncharted contains five separate beurre blanc recipes across five different seafood dishes, which means he returns to the same technique five times and changes the flavour each time. No other cookbook does this, so the comparison between versions is information nobody else can offer.
The one rule that stays the same across all five is cold butter on low heat, added gradually while you keep the pan moving. Let the temperature climb too high and the butterfat separates from the liquid, which leaves you with grease instead of sauce.

minutesThe cream-stabilised beurre blanc from the Iceland chapter of Gordon Ramsay’s Uncharted, where five different versions of this French butter sauce appear across five seafood dishes. This one is the most forgiving for home cooks because the cream holds the emulsion steady while you whisk in the butter.
Ingredients
- For the beurre blanc:
60ml (¼ cup) brennivín or aquavit
60ml (¼ cup) white wine vinegar
1 shallot, finely minced
1 garlic clove, sliced
60ml (¼ cup) double cream (heavy cream)
225g (1 cup / 2 sticks) cold unsalted butter, cut into 2.5cm (1 in) cubes
Fine sea salt
Freshly ground black pepper
Directions
- Build the reduction: Combine the brennivín, vinegar, shallot and garlic in a small saucepan over medium-low heat. Bring to a low boil and let it reduce until only about 2 tablespoons of liquid remain, which concentrates all the flavour into a sharp, intense base.
- Stabilise with cream: Pour in the double cream and simmer for 1 minute so the milk proteins give the emulsion a stable foundation before the butter goes in.
- Whisk in the butter: Drop the heat to low and add a few cubes of cold butter at a time, whisking steadily so each piece melts into the sauce before the next goes in. Keep swirling the pan between additions to stop the sauce from overheating and splitting.
- Season and strain: Once all the butter is incorporated and the sauce looks thick and glossy, season with salt and pepper, then pour through a fine mesh strainer to catch the shallot and garlic.
Notes
- This recipe is from the grilled salmon chapter in Gordon Ramsay’s Uncharted. The original calls for brennivín (Icelandic aquavit) but dry white wine works as a direct substitute if you cannot find it. This is the only one of his five Uncharted beurre blanc recipes that uses cream, which makes the emulsion more stable and more forgiving. The Brennivín version does not include lemon in the sauce itself, though his seaweed beurre blanc in the same book finishes with lemon zest and juice after straining. If you want a classic lemon butter sauce finish, squeeze in half a lemon after step 4. Beurre blanc does not store or reheat. Make it while your fish rests and serve immediately.
FAQs
What is the difference between beurre blanc and lemon butter sauce?
Beurre blanc is a specific French technique where you reduce wine or vinegar with shallots until the liquid is nearly gone, then whisk cold butter into that concentrated base to build a warm emulsion. The name translates to “white butter” and the method goes back to Loire Valley cooking.
Lemon butter sauce is really just a flavour description, so it can mean anything from a proper beurre blanc with citrus to nothing more than melted butter with lemon squeezed in. Ramsay adds citrus to only two of his five Uncharted versions: the seaweed beurre blanc finishes with lemon zest and juice while the satsuma version builds orange directly into the reduction. The other three have no citrus at all, which shows he thinks of beurre blanc as a technique rather than a fixed recipe.
What fish goes best with lemon butter sauce?
Ramsay pairs his beurre blanc with everything from oily salmon and firm white redfish to scallops, lobster and oysters across the five Uncharted recipes, so the sauce suits any seafood with enough flavour to hold its own against all that butter. The Brennivín version sits alongside the whole grilled salmon in the Iceland chapter while the brown beurre blanc covers poached lobster, so both rich and delicate proteins work.
For a weeknight dinner, spooning this over crispy pan-seared salmon is the easiest route because the acid in the reduction cuts through the fat in the skin. If you’re going the shellfish direction, his seaweed beurre blanc goes specifically with hand-dived scallops, so seared scallops are another natural pairing.
Why does Ramsay add cream to some beurre blanc recipes but not others?
The Brennivín version from the Iceland chapter is the only one of five where he stirs in 60ml (¼ cup) of double cream before the butter goes in. Cream acts as a safety net because the milk proteins help hold the emulsion together, which means the sauce is far less likely to split if the heat creeps up while you’re whisking.
His other four versions skip the cream entirely and rely on swirling the pan gently to keep the temperature steady. The brown beurre blanc for poached lobster layers in pre-made brown butter after the emulsion is built, while the gin version stays deliberately lean so it coats the seaweed tagliatelle rather than drowning it. Each variation is tuned to the dish it goes with.
How is beurre blanc different from hollandaise?
Both are French butter emulsion sauces but the method is completely different. Beurre blanc uses no eggs at all, just cold butter whisked into a hot acid reduction, so the texture is looser and sits lightly over fish without cloaking it. The hollandaise from Ultimate Home Cooking beats egg yolks over a bain-marie as the emulsifier, which makes it thicker and more stable but heavier.
The practical difference for a home cook is that beurre blanc is faster and sharper while hollandaise clings and coats, which is why hollandaise suits eggs Benedict and steamed asparagus. Ramsay’s béarnaise from Bread Street Kitchen follows the same egg-yolk method but builds on a tarragon-vinegar reduction, so it sits between the two in terms of weight and punch.
Can you make beurre blanc ahead of time?
No, and claiming it keeps for days is not honest. Beurre blanc is an unstable emulsion that starts separating the moment it cools, which is exactly why Ramsay builds every one of his five versions right before plating. None of the Uncharted recipes suggest making it in advance.
The upside is the whole sauce takes about 10 minutes, so you start it while your fish rests after cooking and both finish at the same time. If you need to hold it for a few minutes, keep the pan somewhere warm but not hot and give it a gentle swirl now and then. Anything past 15 minutes and the butter pools on the surface.
