Steps
Before you start
- The chai concentrate must be completely cold before blending, or it will melt the ice cream and make a thin shake. Allow about 40 minutes of cooling and chilling.
- Chill your serving glasses in the freezer while the chai cools.
- Take the ice cream out of the freezer about 5 minutes before blending so it scoops easily but is still firm.
- Lightly crush the cardamom pods, cloves and peppercorns with the flat of a knife or a mortar and pestle so they release flavor.
Crush the spices
- Place the cardamom pods, cloves and peppercorns on a cutting board and press down with the flat side of a knife, or crush in a mortar, until the pods split open and the cloves crack.
- Break the cinnamon stick in half.
- Finely grate the ginger, skin on.

Ready when: Pods are split and the spices smell fragrant
Tip: Crushing exposes the seeds and oils; uncrushed spices give a much weaker chai.
Simmer the spices
- In a small saucepan combine the water, ¼ cup (60 ml) milk, crushed spices, cinnamon and grated ginger.
- Bring to a gentle boil over medium heat, then reduce to medium-low and simmer for 3 minutes.

Ready when: The liquid is light tan and smells strongly of ginger and cardamom
Tip: Watch the pan; milk foams up and boils over quickly.
Steep the tea
- Add the black tea and brown sugar.
- Simmer over medium-low heat for 3 minutes, stirring once or twice, until the sugar dissolves and the liquid is deep amber-brown.
- Remove from the heat.

Ready when: Liquid is deep amber-brown and the sugar has fully dissolved
Tip: Don't simmer longer than 3 minutes or the tea turns bitter.
Strain the concentrate
- Pour the mixture through a fine-mesh strainer into a heatproof jug, pressing the solids with a spoon to extract all the liquid.
- You should have about ½ cup (110–120 ml) of concentrate.
- Discard the solids.

Ready when: About ½ cup (110–120 ml) of clear, dark liquid
Tip: If you have noticeably less, top up with a splash of cold milk before chilling.
Chill completely
- Let the concentrate cool for 10 minutes at room temperature, then refrigerate for at least 30 minutes (or freeze for 15–20 minutes).
- Chill your glasses in the freezer at the same time.

Ready when: Concentrate feels cold to the touch, with no warmth at all
Tip: Even slightly warm chai will turn the shake thin and foamy.
Blend the shake
- Add the ¼ cup (60 ml) cold milk, chilled chai concentrate and vanilla ice cream to the blender, in that order.
- Blend on low for 10 seconds, then on high for 20–30 seconds, until smooth and thick with no ice cream chunks.

Ready when: Thick, pourable, uniformly light caramel color, with no lumps
Tip: Don't over-blend; it warms and thins the shake. For a thicker shake, add one more scoop of ice cream.
Serve right away
- Pour into the chilled glasses and dust the tops with the ground cinnamon, if using.
- Serve immediately with wide straws or long spoons.

Good to know
Tips
- Make the chai concentrate stronger than you'd drink it; the ice cream dilutes and mutes the spice flavors.
- For a thicker shake, freeze the cooled chai concentrate in an ice cube tray for 2 hours and blend the cubes in with the milk and ice cream.
- Use whole spices rather than pre-ground for a brighter, cleaner flavor.
- Taste before serving; if you want it sweeter, blend in 1 tsp honey.
Make ahead
Make the chai concentrate up to 3 days ahead and keep it in a covered jar in the refrigerator. Blend the shake just before serving.
Storage & reheating
Best served immediately. Leftover blended shake can be frozen in a covered container for up to 1 week; let it sit at room temperature for 5–10 minutes and re-blend with a splash of milk to restore the texture. Chai concentrate keeps 3 days in the fridge in a sealed jar. Do not leave the shake at room temperature.
Substitutions
- vanilla ice cream → dairy-free vanilla ice cream (oat or coconut). Use oat or almond milk for the milk too; coconut-based versions taste slightly more tropical.
- loose-leaf black tea (Assam or CTC) → 1½ tbsp (4 g) decaffeinated black tea. Gives the same flavor with less caffeine.
- light brown sugar → honey or maple syrup. Use 1 tbsp (15 ml) and stir in after removing from the heat.
- green cardamom pods → ⅛ tsp ground cardamom. Use in place of the pods and add with the tea; the concentrate may be slightly cloudy.
