While Burgundy’s mustard tradition centres on Dijon, the culinary application of mustard across the region’s cooking constitutes a distinctive technique system that deserves attention beyond its role as a condiment. Burgundy produces three distinct styles of mustard, each with specific culinary applications: Moutarde de Dijon (smooth, hot, made with brown mustard seeds, verjuice, and white wine—the all-purpose cooking mustard), Moutarde à l’Ancienne or Moutarde de Meaux (whole-grain, milder, with visible seeds providing textural contrast), and the rare Moutarde de Bourgogne IGP (made exclusively with brown mustard seeds grown in Burgundy and Aligoté wine). The culinary techniques divide into three categories. First, mustard as sauce binder: whisked into a wine reduction, mustard’s mucilage (a natural emulsifier from the seed coating) stabilises butter and cream sauces, allowing them to hold without separation—this is the principle behind Sauce Dijonnaise and Lapin à la Moutarde. Second, mustard as crust: whole-grain mustard spread on rabbit, pork, or salmon before roasting forms a flavourful, slightly crunchy coating that protects the protein from direct heat while seasoning from without. Third, mustard as marinade component: Dijon mustard’s acidity (pH 3.5-4.0) gently denatures surface proteins on meat, improving browning while adding flavour—the Burgundian practice of coating beef in mustard before searing produces a deeper, more even crust. The Moutarderie Fallot in Beaune, the last independent stone-ground mustard maker in Burgundy, produces the finest examples of all three styles using traditional methods that preserve the seed’s volatile allyl isothiocyanate—the compound responsible for mustard’s heat.
Match the mustard style to the application: smooth Dijon for sauces, whole-grain for crusts and finishing, Bourgogne IGP for premium applications. Add smooth mustard to hot sauces off the heat—boiling destroys the volatile compounds that create mustard’s heat and flavour. Use mustard as an emulsifier in vinaigrettes and butter sauces, not just as a flavouring. Whole-grain mustard survives heat better than smooth and is suitable for roasting crusts. Fresh, quality mustard should sting the nose—if it doesn’t, it’s lost its potency.
Seek out Moutarderie Fallot products—their stone-ground process at low temperature preserves the seed’s essential oils far better than industrial steel-roller methods. For the definitive Lapin à la Moutarde, use three tablespoons of Dijon in the braising sauce (added at the end) and one tablespoon of whole-grain stirred in just before serving—the combination provides both heat and textural interest. Make a Burgundian vinaigrette by whisking a generous tablespoon of Dijon mustard into red wine vinegar before adding walnut oil—the mustard emulsifies the dressing beautifully and adds characteristic bite.
Boiling mustard in a sauce, which kills its heat and produces a flat, bitter flavour. Using generic yellow mustard instead of proper Dijon or Bourgogne—the flavour profiles are completely different. Storing mustard in warm conditions or keeping open jars too long—the volatile compounds degrade rapidly. Adding too much mustard to a sauce, overwhelming other flavours—it should support, not dominate. Confusing Dijon mustard (a style) with mustard from Dijon (a geographic origin)—most ‘Dijon mustard’ is now made elsewhere.
