- The butter separated (sauce broke).
- Base was too hot, or you added butter too fast. A tablespoon of ice-cold water and wild whisking sometimes saves it.
- Stayed too thin.
- You didn't reduce the beer enough at the start. Thicken further or use a tiny bit of cornstarch.
Spicy Beer Mustard Sauce
This sauce is an elegant dance of physics and chemistry: emulsion. Beer (water-based) and butter (fat-based) don't naturally like each other. Natural compounds in mustard and slow addition of cold butter help create a stable, creamy sauce without cream or flour. The hoppy bitterness of beer counterpoints the honey's sweetness perfectly.

Instructions
1
✓
Put beer, garlic, honey, and chili in the saucepan. Boil and cook until reduced by half.
Tip: This concentrates flavors and evaporates alcohol.
2
✓
Reduce heat to minimum. Whisk in the mustard.
Tip: Mustard dislikes high heat; it can lose potency and turn bitter.
3
✓
Remove from heat. Now the trick: while whisking constantly, add COLD butter cube by cube.
Tip: This is called 'mounting with butter' (monter au beurre). Cold butter melts slowly, forming an emulsion with the liquid for a glossy, thick sauce.
