Fresh Mint Syrup
Recipe Guy
Blanched fresh mint | Naturally green | Refrigerator recipe
Fresh leaves make this mint syrup green as well as fragrant. A brief blanch, immediate ice bath, thorough drying, and a cool blend keep the method deliberate. The syrup is strained before bottling, leaving a pourable mint concentrate without large pieces of leaf.
About This Recipe
The sugar syrup and mint are prepared separately before they meet in the blender. That means two cooling steps: one ice bath for the blanched leaves and another for the saucepan. Have both planned before starting so the short blanch does not turn into a scramble for ice.
Drying matters because water caught between the leaves joins the measured syrup. Straining matters too: light pressure extracts liquid, while hard squeezing pushes more plant material through. Chill the finished syrup before judging its flavor, as the method specifies.
Ingredient Notes
Mint
Spearmint gives a rounded garden-mint flavor; peppermint is cooler and more assertive. Use unblemished leaves and tender tips without black spots.
Blanch and shock
A very short boil followed immediately by ice water sets the natural chlorophyll better than simmering the leaves in syrup.
Natural color
The first bottle will be naturally green, not neon. It will gradually darken in storage because no artificial coloring is used.
Cool syrup
Blend only after the syrup drops below 90 F. This protects the fresher mint aroma and avoids blending a dangerously hot liquid.
Cooking Notes
- Start the blanching timer when the mint goes into the boiling water, with the ice bath already beside it. Keep the listed fifteen-second step brief and transfer the leaves immediately.
- Check that the syrup is below the stated 90 F before blending. The cooling bath belongs around the saucepan, not inside it; stray bath water dilutes the measured batch.
Fresh Mint Syrup Recipe
A fresh mint syrup made naturally green by briefly blanching the leaves, cooling them fast, and blending them into cooled simple syrup without artificial coloring.
Yield: About 1 1/2 cups, or 24 tablespoons Serving size: 1 tablespoon
Yield note: Carefully dried mint keeps the batch close to 1 1/2 cups. Water clinging to the leaves increases the yield but dilutes the flavor. Fine straining may retain a few tablespoons.

Ingredients
Simple Syrup
- 1 cup (200 g) granulated sugar
- 1 cup (240 ml) water
- 1/16 teaspoon fine salt
Fresh Mint
- 1 1/2 packed cups (30 g) fresh spearmint or peppermint leaves and tender tips
For Blanching and Cooling
- 6 cups (1.4 liters) water for blanching
- 4 cups ice, divided
- 4 cups cold water, divided
Instructions
- Pick through the mint and discard bruised, yellow, or blackened leaves and tough stems. Rinse the mint in cool water, swish to release any grit, and drain.
- Make the first ice bath with 2 cups ice and 2 cups cold water in a medium bowl. Set a mesh strainer and tongs next to the bowl.
- Bring the 6 cups blanching water to a rolling boil. Lower the mint into the water, press it under with the tongs, and blanch for exactly 15 seconds.
- Lift the mint directly into the ice bath and swish for 1 minute to stop the cooking. Drain, squeeze very gently, and pat thoroughly dry between clean kitchen towels.
- Combine the sugar, 1 cup syrup water, and salt in a small saucepan. Stir over medium heat until clear, bring to a gentle simmer, and cook for 1 minute.
- Make a second ice bath with the remaining 2 cups ice and 2 cups cold water. Set the saucepan in the bath without letting water enter it, and stir the syrup until it cools below 90 F, about 10 minutes.
- Put the cooled syrup and dried blanched mint in a blender. Blend for 30 to 45 seconds, stopping once to scrape the sides, until the leaves are very finely chopped and the syrup is evenly green.
- Pour through a fine-mesh strainer lined with damp cheesecloth into a clean bowl. Let it drain for 5 minutes and press lightly; hard squeezing makes the syrup cloudier and more vegetal.
- Transfer the strained syrup to a clean container, cover, label, and refrigerate immediately. Chill fully before evaluating the flavor, which becomes rounder after about 2 hours.
Nutrition Estimate
Calculated from the full amount of sugar and salt divided by the stated yield; strained mint contributes negligible energy at this serving size. Actual values vary with straining loss, final yield, ingredient labels, and portion size; this is an estimate, not a regulated nutrition label.
Tips For The Best Fresh Mint Syrup
- Time the blanch: Fifteen seconds is enough to soften the leaves. A long boil cooks away freshness and shifts the color toward olive.
- Dry the mint: Water hidden between the leaves weakens the measured syrup and shortens the flavor.
- Blend cool: Hot liquid creates dangerous steam pressure in a blender and drives off the aroma this method is designed to keep.
- Add citrus at serving: Lemon or calamansi brightens a mint drink, but storing acid in the bottle can dull the natural green more quickly.
- Freeze while bright: If you will not use the syrup within 4 days at 40 F or below, freeze portions on the first day. The four-day limit applies to both the blended and steeped versions.
How To Serve And Store
Serving: Use 1 tablespoon in iced tea, lemonade, calamansi coolers, sparkling water, coffee, or a cocktail. It also works over fruit salad, melon, chocolate desserts, or shaved ice.
Refrigerate: Keep covered at 40 F or below and use within 4 days. Freeze extra syrup in small portions for longer storage.
Freeze: Freeze in 1-tablespoon portions for up to 2 months. Thaw in the refrigerator; the color may soften, but the flavor remains useful.
Safety: This fresh-herb syrup is not shelf-stable and is not a canning recipe. Keep it refrigerated, use clean utensils, and discard it for mold, gas, fermentation, or a slimy texture.
Common Questions
Do I have to blanch the mint?
No. For a pale, clear syrup, add unblanched mint to the hot syrup off heat, cover for 20 minutes, and strain. The flavor will be softer and the syrup will not be green.
Should I use spearmint or peppermint?
Spearmint is the most versatile for lemonades and mixed drinks. Peppermint has a colder, stronger finish that pairs especially well with chocolate.
Why did the green color fade?
Natural chlorophyll changes with time, heat, light, and acid. Keep the syrup cold and covered, and freeze portions early if color matters.
Can I add lemon juice?
Add lemon or calamansi to the finished drink rather than the storage bottle. That keeps the syrup more flexible and slows acid-related color dulling.
Can I store mint syrup at room temperature?
No. Fresh plant material and water make it a refrigerator syrup even though it contains a full cup of sugar.
Why did the mint syrup turn cloudy after straining?
Hard squeezing can push fine leaf material through the cheesecloth. Let the syrup drain first and press lightly, accepting a little loss in yield rather than forcing every last drop from the mint.
Does the blanching water become part of the mint syrup?
No. The six cups are for blanching and are separate from the one cup used with the sugar. Drain and dry the cooled leaves before blending them into the prepared syrup.
