Cuban Mustard Sauce Recipe: Zesty Garlic-Kissed Tang for Sandwiches

This sauce transforms any sandwich with its bold, tangy flavor. A perfect balance of mustard, garlic, and citrus creates a versatile condiment.

Easy to make with simple ingredients, it keeps well in the fridge. Use it on Cubanos, burgers, or as a dipping sauce.

Ingredients for Cuban Mustard Sauce

Bold flavors come from a simple blend of mustards, citrus, and garlic. Ready in minutes.

The mustards are key here. French’s Classic Yellow delivers that iconic tang, while Grey Poupon Dijon adds depth. Look for mustards without added sugar to control the sweetness yourself. Most grocery stores carry both—Whole Foods has great organic options. The garlic should be fresh, not jarred, for the sharpest bite that balances the acidity.

No lime juice? Lemon juice at equal amount works, though it’s slightly less authentic. Swap agave for maple syrup or date syrup if you prefer. The orange juice can be omitted, but it adds that signature Cuban brightness. If you’re out of Dijon, whole grain mustard at the same quantity brings a nice texture, though it’ll be less smooth.

This keeps beautifully in the fridge for up to 2 weeks. The flavors actually improve after a day as they meld together. Store in a clean, airtight jar—glass is best to preserve the freshness of the citrus and garlic.

Step-by-Step Instructions for Cuban Mustard Sauce

This straightforward method combines bold flavors with minimal effort for consistent results.

Step 1: Mince the Garlic Finely

Peel the 4 cloves Garlic Cloves and mince them as finely as possible. The smaller the pieces, the more evenly the garlic flavor will distribute throughout the sauce. I prefer to use a chef’s knife and the rock-and-chop method for consistency.

Fine mincing prevents any large garlic chunks in the final sauce, which can be overpowering in a single bite. Set the minced garlic aside while you prepare the remaining ingredients.

Step 2: Whisk Together the Mustards and Liquid Ingredients

In a medium bowl, combine the 0.5 cup Yellow Mustard, 0.25 cup Dijon Mustard, 2 tbsp Lime Juice, 1 tbsp Orange Juice, and 1 tsp Agave Nectar. Whisk vigorously until the mixture is completely smooth and uniform in color.

The lime and orange juices will help thin the mustards slightly while adding that signature Cuban citrus tang. The agave nectar balances the acidity with a subtle sweetness. Ensure there are no visible streaks of mustard or separation in the mixture.

Step 3: Emulsify with Olive Oil

While continuing to whisk, slowly drizzle in the 2 tbsp Olive Oil in a thin, steady stream. This gradual addition is crucial for creating a stable emulsion that won’t separate.

You’ll notice the sauce begin to thicken and become glossy as the oil incorporates. If the oil pools on the surface, stop adding and whisk more vigorously until it’s fully combined before continuing. The finished sauce should have a smooth, creamy consistency.

Step 4: Season and Incorporate the Garlic

Add the minced garlic, 0.5 tsp Salt, and 0.25 tsp Ground Black Pepper to the mustard mixture. Stir well to distribute all ingredients evenly. Let the sauce sit for 5 minutes to allow the garlic flavor to meld with the other components.

Taste and adjust seasoning if needed, though the recipe is balanced as written. The salt enhances all flavors, while the pepper adds a subtle warmth that complements the tangy mustards. The garlic will mellow slightly during this short rest period.

Wine and Beer Pairings for This Recipe

Crisp White Wines

A Sauvignon Blanc from New Zealand offers bright citrus notes that echo the lime in this sauce. The acidity cuts through the richness while complementing the garlic. I recommend Kim Crawford or Oyster Bay for reliable quality. 🍷

Light Lager Beers

Cuban lagers like Cristal or Tropical Hatuey are perfect matches—their crisp, clean profiles let the mustard and citrus shine. For domestic options, Corona Premier or Modelo Especial work beautifully with their light body and subtle sweetness.

Spanish Varietals

An Albariño from Rías Baixas delivers zesty lemon and peach flavors that pair wonderfully with the tangy, garlicky sauce. Try Pazo de Señorans for a classic example. The wine’s mineral edge enhances the sauce’s complexity.

Wheat Beers

A Hefeweizen with its banana and clove notes provides an interesting contrast to the sharp mustard. Weihenstephaner or Paulaner are excellent German options. The beer’s effervescence cleanses your palate between bites. ✨

Rosé Options

Dry Provençal rosé offers red fruit flavors with a crisp finish that balances the sauce’s boldness. Look for Whispering Angel or Miraval. Serve well-chilled for the best experience.

Non-Alcoholic Pairing

For a zero-proof option, try sparkling limeade with a pinch of salt on the rim. The bubbles and citrus mirror the sauce’s acidity, while the sweetness complements the mustard’s tang. I make mine with fresh lime juice and agave syrup.
