How to Use Bordier Butter: The Essential Techniques

If you've brought Bordier butter into your kitchen, you already know its not an everyday butter.

This guide on how to use Bordier butter focuses on the small choices that make it shine—when to add it, how to handle the heat, and which style to choose (Doux, Demi-Sel, or flavored) depending on the finish you wish to get.

The guiding principle: preserve the aroma.

Whether you are using Doux, Demi-Sel, or a flavored butter, the most reliable rule is the same: finish gently.

High heat can mute aroma and push butter past its most refined moment. We recommend adding flavored butter off the heat to preserve its aroma and delicate flavor. The same principle applies to Bordier’s classic butters when aiming for a clean, polished finish.

Start with the right butter

Doux (unsalted)

Choose Doux when you want control.

• Best for baking and pastry
• Ideal when your dish already has salt from cheese, cured meats, anchovies, or reductions
• The cleanest choice for sauces where you want the main ingredient to stay in focus

Demi-Sel (semi-salted)

Choose Demi-Sel when you want immediate savor.

• Best for bread, warm vegetables, eggs, potatoes
• Excellent as a finishing butter when you want seasoning built in
• A strong first choice if you want one butter that works across many everyday uses

Flavored Bordier butters

Choose flavored butters when you want a specific finish (citrus lift, marine brine, smoke, gentle heat, sweet aromatics).

Technique 1: the gloss finish

This is the fastest way to get a clean, polished result.

• Cook the food fully
• Turn the heat off
• Add a small amount of Bordier butter and swirl until it melts into a thin coating

Think of it as a sheen, not a sauce.

Best with: Demi-Sel, Yuzu, Olive Oil & Lemon, Seaweed, Smoked Salt

Technique 2: mount the sauce (monter au beurre)

This is the classic restaurant move: butter added at the end to enrich, smooth, and unify.

Monter au beurre refers to adding very cold butter in small pieces to create a sauce that becomes glossy, dense, and unctuous. It should be done off the heat or over very low heat to encourage proper emulsification.

Use it when you have pan juices, a reduction, or a simple base that needs body.

Best with: Doux (for maximum control), Demi-Sel (for built-in seasoning), Onion (Roscoff), Wild Garlic & Kampot Pepper, Espelette, Truffle (if using)

Technique 3: the warm spread

Sometimes the best use is the simplest: temperature and texture.

Let the butter soften briefly, then spread in a thin first layer. Add a second pass only where you want intensity.

Best with: Demi-Sel, Buckwheat, Madagascar Vanilla, Onion (Roscoff)

Choosing butter by the desired finish

Clean, neutral richness

• Doux: pure butter character, no added seasoning

Seasoned, classic butter finish

• Demi-Sel: savory and immediate, especially good on warm starches and vegetables

Citrus lift

A bright finish that reads immediately.

• Yuzu: sharper, more aromatic
• Olive Oil & Lemon: rounder, softer citrus

Marine/briny

• Seaweed: A sea-salt effect with a distinct coastal note.

Savory depth

Aromatic, rounded, and especially good on vegetables and warm starches.

• Onion (Roscoff)
• Wild Garlic & Kampot Pepper

Smoke and gentle heat

Structure, contrast, and a longer finish.

• Smoked Salt
• Espelette

Sweet aromatics

A finishing note that feels precise, not sugary.

• Madagascar Vanilla
• Buckwheat

Three signature finishes (not recipes)

1. Roasted fish + Doux, mounted into the pan juices. Reduce the juices slightly, then mount with cold pieces of Doux off-heat for a clean, glossy finish.
2. Warm potatoes + Demi-Sel gloss. Finish off-heat with a small amount, then taste before adding extra salt.
3. Green vegetables + Onion butter. Add at the end so the flavor stays rounded, not sharp.

Common mistakes

• Adding the butter too early: you lose aroma and finesse
• Using too much butter: start small; add a second pass if needed
• Seasoning before tasting: let the butter melt, then decide
