Full Ingredients

Classic British Mint Sauce

• Fresh mint leaves: 1 packed cup (30 g), finely chopped (stems discarded)
• Boiling water: 1/4 cup (60 ml), freshly boiled at 100°C
• Granulated sugar: 1 tbsp (12 g)
• Malt vinegar: 1/4 cup (60 ml), plus up to 1 tbsp (15 ml) more to taste
• Fine sea salt: 1/8 tsp
• Optional: pinch freshly ground black pepper

Optional Adjustments

• For a sweeter balance: add up to 1 additional tsp (4 g) sugar
• For extra tang: add 1–2 tsp (5–10 ml) malt vinegar

Step-by-Step Instructions

Step 1: Prep and dry the mint

Rinse a large bunch of mint under cool water. Shake off excess moisture, then pat leaves very dry with a clean tea towel or paper towels. Pull the leaves from the stems until you have 1 packed cup (30 g) of leaves. Dry leaves chop more cleanly and help keep the sauce bright.

Step 2: Chop and bruise for maximum aroma

Finely chop the mint. For extra fragrance, lightly bruise the chopped mint by pressing it under the flat side of your knife or giving it a quick press in a mortar (do not pound to a paste). This helps release essential oils while keeping a leafy texture.

Step 3: Make a quick hot syrup

In a heatproof jug or small bowl, add the sugar. Pour in the boiling water (100°C) and stir until the sugar dissolves, about 20–30 seconds. This brief hot soak softens the mint later and rounds the vinegar’s bite.

Step 4: Combine and season

Stir the chopped mint into the hot syrup, then add the malt vinegar and salt. Mix thoroughly so the mint is evenly suspended. If using, add a pinch of black pepper. The liquid should be thin, with vivid green flecks of mint in a pale amber base.

Step 5: Steep to bloom flavor

Let the sauce stand at room temperature for 15 minutes. During this time, the mint softens and the flavors meld into a classic tangy-sweet profile. For an even deeper mint character, you can chill it for up to 1–2 hours before serving.

Step 6: Taste and adjust, then jar

Taste the sauce. If you want more brightness, add 1–2 tsp (5–10 ml) extra malt vinegar. For more sweetness, add up to 1 tsp (4 g) sugar and stir to dissolve. Transfer to a clean jar or small jug for serving.

Pro Tips

• Color saver: dry the mint thoroughly before chopping; excess water can dull the green.
• Sharper or softer: adjust the final splash of vinegar or pinch of sugar to match your palate.
• Leafy, not mushy: chop fine but avoid pulsing in a blender, which bruises the mint too much and muddies the sauce.
• Make it pourable: this sauce should be thin; if it seems too thick, stir in 1–2 tsp hot water.
• Scaling: keep a simple ratio—equal parts boiling water and malt vinegar, sweetened to taste, with plenty of chopped mint.

Variations

• Honey Mint Sauce: Replace sugar with 1 tbsp runny honey; lovely round sweetness and a soft floral note.
• Apple-Mint Sharp: Stir in 2 tbsp unsweetened applesauce and switch to cider vinegar; reduce sugar to 1 tsp.
• Chili-Mint Kick: Add 1–2 tsp very finely minced green chili for gentle heat; keep the sauce thin and bright.

Storage & Make-Ahead

Refrigerate in a clean jar for up to 7 days; flavor deepens after the first day. For longer storage, freeze in ice-cube trays, then transfer cubes to a freezer bag for up to 2 months; thaw in the fridge and stir before serving. If the color darkens slightly over time, a fresh pinch of chopped mint spruces it up.
